Yu-Gi-Oh! summoning rules, chains and timing: the complete guide

In the Yu-Gi-Oh! TCG you get one Normal Summon or Set per turn, while Flip Summons and Special Summons (Fusion, Synchro, Xyz, Link, Pendulum and Ritual) have no rulebook limit; chains resolve backwards from the last card activated, and Tokens can be used for most Summons but never as Xyz Material. That paragraph answers the questions people search for most. The rest of this guide takes one rule question per section, so you can jump straight to the one you need: how each Summon works, what Tokens can and can't do, when a Set card can be activated, how Spell Speed limits responses, what "negate the activation" changes, why some effects miss the timing, and what you may do in the Damage Step. The last sections apply those rules to staple cards such as Ash Blossom, Infinite Impermanence and Nibiru.

Every rule here was checked on 21 October 2026 against Konami's own documents: the Official Rulebook Version 10, which yugioh-card.com still links as the official rulebook, and the "2021 Rules Update" page, which changes part of it. Page numbers in brackets refer to the printed page numbers of that PDF. Card texts come from Konami's official card database. One principle overrides everything else: when a card's text and the basic rules disagree, the card wins (p. 50). Questions about which cards are legal, OCG versus TCG prints or the Forbidden and Limited List are covered in our guide on whether you can play OCG cards in Spanish TCG tournaments.

Every Summon at a glance

Normal Summon, Set and Flip Summon: what counts as what

You can Normal Summon or Normal Set only once per turn in total, but a Flip Summon does not count as your Normal Summon, so yes, you can Flip Summon one monster and Normal Summon another in the same turn. The rulebook groups the ways to put monsters on the field into actions you can do once per turn and actions you can repeat (pp. 24–25). Normal Summon and Normal Set share the single slot. Flip Summons and Special Summons have no limit from the rules (p. 36).

The four actions side by side

• Normal Summon: a monster from your hand goes onto the field in face-up Attack Position (p. 24).
• Normal Set: a monster from your hand goes onto the field in face-down Defense Position. A Set monster is not considered Summoned (p. 24). You can never play a monster from your hand in face-up Defense Position.
• Tribute Summon: a Level 5 or 6 monster needs 1 Tribute and a Level 7 or higher monster needs 2. A Tribute Summon is still your one Normal Summon. Doing the same face-down is a Tribute Set, and the monster is not considered Summoned either (p. 24).
• Flip Summon: you turn a face-down Defense Position monster into face-up Attack Position without a card effect. It has to go to Attack Position, and you can't do it in the turn that monster was Set (p. 25).

Being flipped face-up is not always a Flip Summon

A face-down monster can also be turned face-up because it is attacked or because a card effect flips it. Those are not Flip Summons. FLIP effects activate in all three cases: Flip Summoned, attacked while face-down, or flipped by an effect (p. 11). If it was attacked, the FLIP effect activates after damage calculation (p. 41).

Worked example

Turn 1: you Set a Level 4 monster. Turn 3: in Main Phase 1 you Flip Summon it, then Normal Summon a different Level 4 monster from your hand. Both are legal. What you can't do that turn is Normal Summon one monster and also Normal Set another. The flipped monster also can't change position again that turn, because a Flip Summon is itself a change of battle position (p. 36).

Common mistakes

• Treating a Set monster as Summoned. Effects that care about a monster being "Summoned" don't see a Normal Set.
• Flip Summoning a monster in the same turn you Set it.
• Thinking a Tribute Summon is a second, separate Normal Summon.
• Normal Summoning in Main Phase 1 and expecting another one in Main Phase 2. The limit is per turn, not per phase (p. 40).

Changing battle position: the three restrictions

During your Main Phase you can change each monster's battle position once per turn, except a monster that was played onto the field this turn, a monster that attacked this turn (in Main Phase 2), or a monster whose position you already changed this turn. Those are the three exceptions the rulebook lists (p. 36). Flip Summoning counts as a change of position, and so does switching a face-up monster between Attack and Defense.

• A monster you Normal Summoned or Special Summoned this turn can't be switched by hand in that same turn.
• A monster that attacked in the Battle Phase stays in Attack Position through Main Phase 2.
• Main Phase 2 doesn't reset anything: a limit used in Main Phase 1 stays used (p. 40).
• Link Monsters have no DEF. They can never be in Defense Position, not even through a card effect, and they can't be flipped face-down (p. 14).

Position changes made by a card effect follow that card's text, not this manual limit, because card text takes priority over the basic rules (p. 50). Changing a battle position is not an effect activation either, so nobody can chain to it (p. 51).

Properly Summoned: when you can revive a monster

A monster that says it "must first be Special Summoned" in a particular way, and Fusion, Synchro, Xyz and Link Monsters, can only be revived from the Graveyard (or banishment) by another card's effect if they were first properly Summoned. The rulebook gives the standard example: a Synchro Monster sent from the Extra Deck straight to the Graveyard was never Synchro Summoned, so a Spell can't Special Summon it from there (p. 25).

Konami's card-text article on Special Summons adds two details (PSCT part 5). First, if the Summon of such a monster is negated, it goes to the Graveyard without having been properly Summoned, so it can't be revived either. Second, monsters with a built-in Summon but no "must first" wording, such as Cyber Dragon, aren't affected and can be revived normally. The Konami EU Tournament Policy (v2.5, in effect since 5 September 2025) uses this as an example of an illegal play that has to be retracted: Monster Reborn targeting Destiny HERO - Plasma, which must be Special Summoned through its own effect.

Three histories of the same Synchro Monster

Monster Reborn reads "Target 1 monster in either GY; Special Summon it." Because it targets at activation, picking a monster that can't be revived makes the whole activation illegal, which is how the policy example treats it: the card goes back to the hand.

Fusion, Synchro, Xyz and Link: how each Extra Deck Summon works

Fusion needs a card such as Polymerization plus the listed materials; Synchro needs one face-up Tuner and face-up non-Tuners whose Levels add up exactly; Xyz needs face-up monsters with the same Level; and Link needs face-up materials that match the recipe and the Link Rating. All four are Special Summons and start in the Extra Deck (pp. 18–25). Since the 2021 Rules Update, Fusion, Synchro and Xyz Monsters can be Summoned from the Extra Deck to any of your Main Monster Zones. Link Monsters, and Pendulum Monsters coming from the Extra Deck, still need the Extra Monster Zone or a zone a Link Monster points to.

Fusion

You activate the Summoning card, send the materials to the Graveyard, then place the Fusion Monster on the field (p. 22). If another effect sends the materials somewhere other than the Graveyard, the Fusion Summon still happens (p. 22). The card that Fusion Summons decides where the materials may come from: Polymerization says "using monsters from your hand or field", while Super Polymerization says "using monsters from either field".

Synchro

During your Main Phase, 1 face-up Tuner plus any number of other face-up monsters you control, whose Levels add up exactly to the Synchro Monster's Level, are sent from the field to the Graveyard (pp. 20–21). A Level 3 Tuner and a Level 2 non-Tuner make a Level 5 Synchro Monster. A Synchro Summon doesn't start a chain (Fast Effect Timing page).

Xyz

You stack face-up monsters of the same Level and place the Xyz Monster on top (pp. 18–19). Xyz Monsters have a Rank, not a Level. The materials stay under the monster; the Xyz Materials section explains what that changes.

Link

You send face-up monsters from your field to the Graveyard, and they must match the material line printed on the card (pp. 12–13). The Link materials section covers how the numbers add up.

Where they can go after the 2021 update

The Version 10 rulebook pages still say every Extra Deck Summon goes to the Extra Monster Zone or a linked zone. The 2021 update is the newer document and replaces that for Fusion, Synchro and Xyz. Monsters that started in the Extra Deck but are Summoned later from the Graveyard or from banishment go to the Main Monster Zones and don't need a Link Monster (p. 14).

Common mistakes

• Using a face-down monster as Synchro, Xyz or Link material. All three procedures ask for face-up monsters.
• Counting a Synchro total that overshoots the target Level. The sum has to be exact.
• Playing a Link Monster into an unlinked Main Monster Zone because the 2021 update freed the other three types.

Link materials and Link Rating

The Link Rating is both the number of Link Arrows and the number of materials a Link Summon needs, and a Link Monster used as material can count as 1 material or as its whole Link Rating, never a number in between. The rulebook sets three conditions that must all be true (p. 15):

1. The materials add up to the Link Rating, with each Link Monster counted as 1 or as its own rating.
2. The number of materials meets the count in the material line ("2+", "3", and so on).
3. The materials match every other requirement in the line, such as "Effect Monsters" or a specific Type.

Worked example: Decode Talker

Decode Talker is Link 3 with the material line "2+ Effect Monsters". Three possible boards:

• Three face-up Effect Monsters: 1 + 1 + 1 = 3, three materials, all Effect Monsters. Legal.
• A Link-2 Effect Monster plus one more Effect Monster: 2 + 1 = 3 with two materials, which meets "2+". Legal. This is the example the rulebook itself gives (p. 14).
• One Effect Monster plus a Token: 1 + 1 is only 2, and a Token is a Normal Monster (p. 49), so it isn't an Effect Monster anyway. Illegal on both counts.

Tokens and Trap Cards treated as monsters can be Link Material when they meet the requirements (p. 15). Link Monsters always stay in Attack Position (p. 14). A Link Monster's red arrows point to zones; a monster in one of those zones is "linked", and two Link Monsters pointing at each other are "co-linked" (p. 12).

The Konami EU Tournament Policy shows a real misplay: Knightmare Phoenix needs two monsters with different names, so a Link Summon using two copies of the same card has to be retracted. Read the whole material line, not only the number.

Xyz Materials and detaching

Xyz Materials are attached under the Xyz Monster and are not treated as cards on the field; detaching one puts it in the Graveyard, but it was never "sent from the field". The rulebook defines detaching as taking one of the stacked cards and putting it in the Graveyard (p. 19), and says materials are not cards on the field (p. 51). That second line explains most disputes:

• A monster that becomes Xyz Material leaves the field without activating its "leaves the field" effects (p. 51).
• A detached material didn't go from the field to the Graveyard, so an effect such as "When this card is sent from the field to the Graveyard" doesn't trigger from detaching.
• When the Xyz Monster leaves the field, all its materials go to the Graveyard. If it is flipped face-down or changes control, the materials stay attached (p. 51).
• Tokens can never be Xyz Material (p. 49).

Is detaching a cost?

Look at the semicolon. Konami's example card Adreus, Keeper of Armageddon reads "Once per turn: You can detach 1 Xyz Material from this card to target 1 face-up card your opponent controls; destroy it." Detaching comes before the semicolon, so it is a cost paid at activation (PSCT part 4). If the effect is negated later, the material isn't returned, because costs are never refunded (glossary, p. 54). An Xyz Monster with no materials left simply can't pay a detach cost.

Pendulum Summon: scales, zones and the Extra Deck

To Pendulum Summon, place two Pendulum Monsters as Spells in your leftmost and rightmost Spell & Trap Zones, then once per turn in your Main Phase Special Summon any number of monsters whose Levels are strictly between the two Pendulum Scales, from your hand and face-up from your Extra Deck. With Scales of 1 and 8, you can Summon Levels 2 to 7; Levels 1 and 8 themselves are not allowed (pp. 16–17).

Step by step

1. In your Main Phase, activate a Pendulum Monster Card as a Spell in your leftmost Spell & Trap Zone and another in your rightmost one. Those zones become Pendulum Zones while the cards are there (pp. 4–5, 17).
2. Declare the Pendulum Summon.
3. Special Summon as many monsters from your hand, and as many face-up Pendulum Monsters from your Extra Deck, as you want, as long as each one's Level fits between the Scales (p. 17).

Hand versus Extra Deck

The two sources follow different zone rules. Monsters from your hand can go to any free Main Monster Zone. Pendulum Monsters coming from the Extra Deck must go to the Extra Monster Zone or to a Main Monster Zone a Link Monster points to (p. 17). The 2021 Rules Update kept that restriction for Pendulum Monsters. Without a Link Monster, you can usually bring back only one monster from the Extra Deck per Pendulum Summon, because you normally use only one Extra Monster Zone (p. 5).

Why Pendulum Monsters end up face-up in the Extra Deck

Whenever one of your Pendulum Monster Cards on the field would be sent to the Graveyard, from a Monster Zone or a Pendulum Zone, it goes face-up on top of your Extra Deck instead (p. 17). Those are the cards a later Pendulum Summon can bring back. A Pendulum Monster in your hand isn't face-up in the Extra Deck, but it can be Pendulum Summoned from the hand.

Common mistakes

• Including the Scale numbers themselves. "In between" is exclusive.
• Putting a Pendulum Monster in a middle Spell & Trap Zone and calling it a Scale.
• Bringing three Pendulum Monsters back from the Extra Deck to Main Monster Zones with no Link Monster pointing there.
• Doing a second normal Pendulum Summon in the same turn. Only a card effect that says so allows another.

Ritual Summon: the Ritual Spell and the Tributes

A Ritual Summon uses a Ritual Spell Card plus the matching Ritual Monster in your hand, and you Tribute monsters from your hand or field as the Ritual Spell requires; the Ritual Monster then goes to a Main Monster Zone in face-up Attack or Defense Position. Unlike Fusion Monsters, Ritual Monsters are Main Deck cards (p. 23).

1. With the Ritual Spell, the Ritual Monster and enough Tributes ready, activate the Ritual Spell in your Spell & Trap Zone.
2. If the activation succeeds, Tribute the monsters from your hand or field by sending them to the Graveyard.
3. Place the Ritual Monster in a Main Monster Zone, then send the Ritual Spell to the Graveyard (p. 23).

Reading the requirement

The exact amount comes from the Ritual Spell. Dawn of the Herald, for example, says you "must also Tribute monsters from your hand or field whose total Levels equal exactly 6" to Ritual Summon Herald of Perfection, a Level 6 monster. A Level 4 and a Level 2 work; a Level 4 and a Level 3 don't, because the total has to be exactly 6. Other Ritual Spells set their own requirement, so always use the text of the card you are resolving.

Tributing is not destroying (glossary, p. 55). Effects that trigger when a monster is destroyed don't trigger for Ritual Tributes. Ritual Spells are Spell Speed 1 (p. 45), so you can only activate them in your Main Phase when nothing else is on a chain.

Tokens: which Summons can use them

Tokens can never be Xyz Material, but they can be Link Material when they meet the recipe, and a Token with a Level can be used in a Synchro Summon unless a card says otherwise; because Tokens are Normal Monsters, they never satisfy a requirement for Effect Monsters. The rulebook rules for Tokens (p. 49) are short:

• They appear on the field through a card effect and are never part of your Deck.
• They can't go anywhere except the field. When a Token is destroyed or would return to the hand or Deck, it is simply removed.
• Each one takes up a Monster Zone and is always in face-up Attack or face-up Defense Position.
• They are treated as Normal Monsters and can't be used as Xyz Material.

Summon by Summon

The card that creates a Token often adds restrictions. One official example creates "Shadow Veil Tokens" that "cannot be Tributed or used as Synchro Material". Some Link Monsters also exclude them in the recipe, such as "2+ monsters, except Tokens". Check both texts before planning a combo.

Extra Deck vs Side Deck

The Extra Deck holds up to 15 Fusion, Synchro, Xyz and Link Monsters you can Summon during the Duel; the Side Deck is a separate pile of up to 15 cards you swap with your Main or Extra Deck between Duels of a Match, never during a Duel. Neither one counts toward your 40-to-60-card Main Deck (pp. 2–3; Tournament Policy v2.5).

• The 3-copies limit covers the Main, Extra and Side Deck combined (p. 2).
• Swaps are 1-for-1, and the Side Deck must have exactly the same number of cards before and after (p. 2). In Konami EU events you show the count at the start of the Match and again whenever you side.
• Cards can't move between the Main Deck and the Extra Deck, even through the Side Deck (Tournament Policy v2.5).
• You can't side before the first Duel, and after each round you restore your original Decks (Tournament Policy v2.5).

Forbidden, Limited and Semi-Limited cards count across all three piles too (p. 49). The current list and how it applies in Spain are in our OCG and TCG legality guide.

To look up a specific card, the TradeMatches format legality checker tells you whether it is Forbidden, Limited, Semi-Limited or unlimited in the TCG, along with its OCG status. Run your Side Deck through it too, not just your Main Deck: the copy limit counts all three piles together.

When can you activate a Set Spell or Trap?

A Set Trap Card or a Set Quick-Play Spell can't be activated in the turn it was Set, but from the next turn on, including your opponent's turn; a Set Normal Spell (or other non-Quick-Play Spell) can be activated in your Main Phase even in the turn you Set it, but never in your opponent's turn. That split is on pages 29–31 of the rulebook.

The other conditions still apply. Spell Speed decides whether you can respond to something (see the chain section), and the card's own condition before the colon must be met. A Field Spell can be placed face-down in the Field Zone, and it isn't active until it is flipped face-up (p. 29). Setting a Spell is a way to bluff, but it doesn't make a Normal Spell usable in your opponent's turn (p. 31).

Some cards break the rule in their own text. Infinite Impermanence says "If you control no cards, you can activate this card from your hand", which lets a Trap skip being Set. Without such text, Traps always have to be Set first (p. 30).

Equip Spells and the equipped monster

An Equip Spell gives its effect to one face-up monster (yours or your opponent's, depending on the card) and stays in your Spell & Trap Zone; if that monster is destroyed, flipped face-down or leaves the field, the Equip Card is destroyed, but destroying the Equip Card doesn't destroy the monster. The rulebook describes it on page 29 and in the glossary entries "Equip Cards" and "Equipped Monster" (pp. 53–54).

• The Equip Spell occupies one of your Spell & Trap Zones even when it is equipped to your opponent's monster. If possible, place it behind the equipped monster as a reminder (p. 29).
• "Equip Card" includes Equip Spells, Traps that become equipped (which remain Traps) and monsters equipped to other monsters (which are treated as Equip Spells) (p. 53).
• A Monster Card equipped to another monster can't be moved to a different monster, even by effects that could normally do it. Union monsters equipped by their own effects are the exception (p. 53).
• Equip Spells are Spell Speed 1 (p. 45), so you activate them in your Main Phase, not in response to something.

Worked example: you activate an Equip Spell and attach it to your opponent's monster. Your opponent returns that monster to their hand: the monster has left the field, so the Equip Spell is destroyed and goes to your Graveyard, because it is still your card. If instead they destroy only the Equip Spell, the monster stays on the field and simply loses what the Equip Spell gave it.

Chains and Spell Speed

A chain resolves in reverse order, from the last card activated back to Chain Link 1, and you can only respond with an effect of Spell Speed 2 or higher that is at least as fast as the link before it. When an effect is activated, the opponent always gets the chance to respond. Players keep adding links until both pass, then the chain resolves backwards (pp. 44–47).

The rulebook's own example

Player A activates Heavy Storm (Chain Link 1). Player B responds with a Set Threatening Roar (Chain Link 2). Player A responds with Seven Tools of the Bandit (Chain Link 3). Seven Tools resolves first and negates the activation of Threatening Roar, which then does nothing. Heavy Storm resolves last and destroys all Spell and Trap Cards on the field (p. 47).

Rules people forget

• Spell Speed 1 effects can't be Chain Link 2 or higher, except when several of them trigger at the same time (p. 45).
• When several effects trigger at once, they go on one chain in this order: the turn player's mandatory effects, the opponent's mandatory effects, the turn player's optional effects, then the opponent's optional effects (p. 50).
• Summoning a monster, Tributing, changing a battle position and paying a cost are not activations, so you can't chain to them (p. 51). You can respond to the activation of a card or effect only.
• The turn player has priority at the start of each phase and step (p. 48). Saying "I move to the Battle Phase" gives your opponent the chance to act before the phase ends.
• Costs and targets are handled when each link is activated, and effects are applied when they resolve (PSCT part 3). That is why a target chosen at Chain Link 1 may be gone by the time it resolves.

If you also play Magic, the chain will feel familiar: the stack also resolves the last thing added first, although the rules on what can respond are different. In the TradeMatches keyword glossary you can search for "chain" or "stack" and compare each game's short definition before opening the full explanation.

Target vs choose: when the choice is made

An effect that targets picks its card when it is activated, before the semicolon, so the opponent knows the target before responding; an effect that "chooses" or affects cards without targeting picks them when it resolves. Konami's card-text rules put everything before the semicolon at activation, and everything after it at resolution (PSCT part 3). So "Target 1 face-up monster your opponent controls; negate its effects" (Infinite Impermanence) locks in its monster immediately. Forbidden Droplet's "choose that many Effect Monsters your opponent controls" comes after its semicolon, so the monsters are chosen at resolution and none of them is targeted.

"That target" versus "it"

The resolution wording tells you what still has to be true (PSCT part 4):

• If it says "that target", the targeting requirements must still be met at resolution. Trap Hole destroys "that target", so if the monster no longer has 1000 or more ATK, nothing happens.
• If it says "it", the requirements only had to be met at activation. Adreus destroys "it", so it destroys the card even if it was flipped face-down, as long as it is still on the field.
• If it says "both", every target must still be valid, or the whole effect does nothing.

Protection that says a card "cannot be targeted" only stops effects that target. It does nothing against effects that choose at resolution or that affect every card. Targeting a monster for an attack is a different thing from targeting with an effect (PSCT part 2).

The Konami EU Tournament Policy shows why the timing matters: if the only legal target leaves before you activate, the activation is illegal and is retracted. Its example is Called by the Grave against a monster that banished itself as a cost.

Negate the activation vs negate the effect

Negating the activation means the card or effect was never successfully activated; negating the effect means it was activated but its effect doesn't apply, and in both cases any cost already paid is lost. The rulebook's chain example uses Seven Tools of the Bandit to negate the activation of Threatening Roar (p. 47). Ash Blossom & Joyous Spring instead says "negate that effect". Costs are paid before the activation and are never refunded, even if the activation is negated (glossary, p. 54).

What changes in practice

• Cards that react to activations. An effect that triggers "when a card is activated" sees an activation that resolved with its effect negated, because the activation itself happened.
• Destruction is never automatic. A negated card is only destroyed or banished if the negating card says so. Seven Tools reads "negate the activation and destroy it"; Decode Talker reads "negate the activation, and if you do, destroy that card".
• Continuous negation. Skill Drain negates the effects of face-up monsters but says their effects "can still be activated". The activation still happens, and so do its costs.
• Spell/Trap Cards versus Spell/Trap effects. Activating a Spell or Trap Card means playing it or flipping it face-up; activating a Spell/Trap effect means using an effect of a card already face-up. Konami's Stardust Dragon text names both so it can stop either (PSCT part 6). A card that only mentions one doesn't stop the other.

Worked example

Your opponent activates a Spell Card that adds a card from the Deck to the hand. You can discard Ash Blossom to negate that effect: the Spell still counts as activated and goes to the Graveyard, but nothing is added. A Counter Trap that "negates the activation" would stop the activation itself. Either way, any cost your opponent paid stays paid.

"When" vs "if": missing the timing

An optional effect worded "When... you can" misses the timing if its trigger was not the last thing that happened, for example because something else happened later in the same effect or chain; Konami ties this risk to optional effects worded "When... you can". Konami's article on conjunctions explains that some effects can only be used in response to a trigger that was "the last thing that happened", and that this is usually the case for cards that "CAN" be used "WHEN" something happens (Understanding Card Text, part 7). Another Konami article calls it to "miss the timing" (PSCT part 6).

How the conjunction decides what happened last

Konami's example is Heraldry Change: "Special Summon 1 'Heraldic Beast' monster from your hand, then end the Battle Phase." After it resolves, the last thing that happened is ending the Battle Phase, so cards that activate "when" a monster is Summoned can't be used. Quickdraw Synchron shows the opposite: it says "send 1 monster from your hand to the Graveyard and Special Summon this card", so the send and the Summon are simultaneous and the sent monster's "when... you can" effect doesn't miss the timing (PSCT part 6).

Location changes before the trigger can activate

The 2021 Rules Update added a related rule. If a monster's Trigger Effect meets its condition in the middle of a chain or effect and is "saved for later", but the card changes location (field, Graveyard, hand, banished or Deck) before it gets the chance to activate, it doesn't activate.

Common mistakes

• Treating every "When" effect as missable. Mandatory effects and the other conditions on the card matter too.
• Reading only the trigger card and ignoring the conjunction on the card that caused it.
• Forgetting that a cost before the semicolon happens before everything after it.

The Damage Step: what you can activate

In the Damage Step you can only activate Counter Traps or cards that directly change a monster's ATK or DEF, and only until the start of damage calculation, unless a card's own text names a Damage Step moment. That is the rulebook's limit (p. 41). Konami's Damage Step page splits the step into five moments and lists which card wordings belong to each:

• The Battle Step (declaring attacks) is not the Damage Step. Most Quick Effects and Traps are used there or earlier.
• If a monster appears or leaves before the Damage Step, the attack is replayed: you may attack with the same monster, another one or not at all. The first monster still counts as having declared an attack (p. 38).
• A monster "battled" only if the attack reached damage calculation (glossary, p. 52).

Piercing battle damage

Piercing means that when your monster attacks a Defense Position monster with lower DEF, your opponent takes the difference between your ATK and their DEF as battle damage; without piercing, they take nothing. The glossary defines it that way (p. 54), and the normal rule for attacking a Defense Position monster gives no damage to the defender's controller when you win (p. 43).

Piercing is still battle damage, so it happens only at damage calculation. Konami's card-text article makes this point: the wording doesn't do anything when the attack is declared (PSCT part 2). Against a direct attack, piercing adds nothing; the full ATK is dealt anyway (p. 43). If the defender survives because it can't be destroyed by battle, piercing still deals the difference, because the damage depends on the ATK and DEF comparison, not on destruction.

Destroy vs send to the Graveyard

A card is destroyed only when it goes to the Graveyard through battle or through an effect that destroys; Tributing, discarding, paying a cost or an effect that says "send" puts it in the Graveyard without destroying it. The glossary is explicit: a card returned from the field to the hand or Deck, or sent to the Graveyard as a cost or Tribute, is not destroyed (p. 52), and a Tributed monster is not destroyed (p. 55).

So "cannot be destroyed" protection doesn't stop Tributes, banishing or "send" effects, and an effect worded "if this card is destroyed" doesn't trigger on a Tribute. Effects that ask for "sent to the Graveyard" do trigger on destruction, discards and Tributes (p. 55). "Leaves the field" covers going to the Graveyard, the hand or banishment; a card shuffled into the Deck (Main or Extra, per the 2021 correction) or turned into Xyz Material doesn't activate its "leaves the field" effects (p. 51).

Owner vs controller

The owner is the player who started the Duel with the card in their Deck; the controller is whoever has it on their side of the field right now, and when the card goes to the Graveyard, hand or Deck it always goes to its owner's. That is the glossary's "Control / Possess" entry (p. 52). You control the cards in your Monster Zones, Spell & Trap Zones, Field Zone and Pendulum Zones.

• A monster you take with a control-changing effect moves to your side. If it is destroyed while you control it, it goes to your opponent's Graveyard.
• If you take control of a monster in your opponent's Extra Monster Zone, it moves to one of your Main Monster Zones. When it goes back, it goes to their Main Monster Zone, not the Extra Monster Zone (p. 14).
• An Xyz Monster that changes control keeps its materials (p. 51).
• Your Equip Spell equipped to your opponent's monster is still your card in your zone, and goes to your Graveyard when destroyed.

At the table, keep borrowed cards clearly separated so each copy goes back to the right Deck at the end of the Duel.

Face-down banished cards

A card banished face-down is out of play like any banished card, but it isn't public knowledge in the same way: in Konami EU events, names of face-up banished cards are public, while for a face-down banished card the owner must answer only questions about cards banished during the current turn. The Konami EU Tournament Policy (v2.5) lists "the number and names of the cards in a Duelist's Graveyard and face-up Banished cards" as public knowledge, along with which cards were banished during the current turn. Its own example: Kashtira Fenrir banishes Tearlaments Kitkallos face-down, and in Main Phase 2 of that turn the opponent may ask what was banished and must get a true answer.

Can a face-down banished card come back? Only through an effect that can find it. Most effects that return banished cards ask for a Type, a name or another property, and a face-down card doesn't show any of those. Some cards are written for it: Gizmek Naganaki, the Sunrise Signaler can "add to your hand, 1 of your banished face-down Machine monsters whose ATK equals its own DEF". Read the retrieval card's text before counting a face-down card as gone for good. Banished cards go back to their owners at the end of the Duel for the next one (glossary, p. 52).

Hand limit: six cards at the end of your turn

The hand limit is checked only at the end of your own End Phase: if you have more than 6 cards then, you discard down to 6; you never discard just for drawing a seventh card during the turn. The rulebook puts the check in the End Phase (p. 40). These discards go to the Graveyard and count as discarding (glossary, p. 52), but they are not a card effect. Effects that resolve "during the End Phase" are handled in that phase too, so finish them before you count.

Empty Deck: when you lose

You lose when you have to draw and can't, not when your Deck becomes empty; a player with 0 cards in the Deck keeps playing until a draw is required. The victory conditions say so (p. 32), and the Draw Phase rule repeats it (p. 34). Sending your last card to the Graveyard or banishing it isn't a draw, so it doesn't make you lose by itself. The Extra Deck doesn't count: drawing always comes from the Main Deck. Remember that the player who goes first skips the draw on their first turn (p. 34).

Ash Blossom & Joyous Spring: what it can negate

Ash Blossom negates the effect of a card or effect whose activation includes adding a card from the Deck to the hand, Special Summoning from the Deck, or sending a card from the Deck to the Graveyard; it doesn't touch anything outside those three actions. Its official text: "When a card or effect is activated that includes any of these effects (Quick Effect): You can discard this card; negate that effect." Then the three bullet points, and "You can only use this effect of 'Ash Blossom & Joyous Spring' once per turn."

• It reads the effect, not the cost. Costs are not part of an effect (glossary, p. 53), so a card that sends from the Deck as a cost before its semicolon doesn't qualify for that reason alone.
• It negates the effect, not the activation. The card or effect still counts as activated (see negation).
• Discarding it is the cost, paid at activation. If Ash is negated, it stays in the Graveyard.
• The once-per-turn clause names the card, so you can't use a second copy in the same turn.
• It is a Spell Speed 2 Quick Effect, so it can't respond to a Counter Trap.

How many copies should you run? The opening hand probability calculator already has the Yu-Gi-Oh! format (40-card Deck, 5-card hand). With 3 copies of Ash Blossom, which is not on Konami's Forbidden & Limited List effective 19 October 2026, you will open it 33.8% of the time; going second and counting the card you draw in your first Draw Phase, that rises to 39.4%, although that card arrives after your opponent's first turn.

Infinite Impermanence: hand, column and resolution

Infinite Impermanence targets one face-up monster your opponent controls and negates its effects until the end of the turn; you can activate it from your hand only if you control no cards, and its column effect applies only if it was Set before activation and is still on the field when it resolves. Its text: "Target 1 face-up monster your opponent controls; negate its effects (until the end of this turn), then if this card was Set before activation and is on the field at resolution, for the rest of this turn all other Spell/Trap effects in this column are negated. If you control no cards, you can activate this card from your hand."

• It is a Normal Trap. When Set, it follows the Trap rule: not the turn it was Set (p. 30).
• The monster is chosen at activation, so your opponent knows it before responding.
• The two parts are joined by "then", so the column part happens after the monster's effects are negated and requires that first part to happen (Understanding Card Text, part 7).
• Activated from the hand, it was never Set, so the column part doesn't apply.
• Negating effects doesn't destroy the monster or stop it from attacking.

Nibiru, the Primal Being: counting five monsters

Nibiru checks whether your opponent Normal or Special Summoned 5 or more monsters this turn; it counts monsters, not Summon actions, so one Summon that brings out several monsters adds all of them, and monsters that already left the field still count. Its text: "During the Main Phase, if your opponent Normal or Special Summoned 5 or more monsters this turn (Quick Effect): You can Tribute as many face-up monsters on the field as possible, and if you do, Special Summon this card from your hand, then Special Summon 1 'Primal Being Token' (Rock/LIGHT/Level 11/ATK ?/DEF ?) to your opponent's field (this Token's ATK/DEF become the combined original ATK/DEF of the Tributed monsters). You can only use this effect of 'Nibiru, the Primal Being' once per turn."

• Only Normal and Special Summons count. A Normal Set isn't a Summon (p. 24), and the text doesn't mention Flip Summons.
• It works only during the Main Phase, never in the Battle Phase or the Damage Step.
• Everything after the colon happens at resolution. The Tributes aren't a cost, so your opponent can respond while their monsters are still on the field.
• It Tributes face-up monsters on both sides of the field. Face-down monsters stay.
• Tributing isn't destroying (p. 55), so "cannot be destroyed" doesn't protect against it.
• The Token's ATK and DEF use the original values of the Tributed monsters (p. 54: original ATK is the printed value).

Example: your opponent Normal Summons one monster and then makes four separate Special Summons of one monster each. That is five monsters, so Nibiru's condition is met for the rest of that turn's Main Phases, even if some of those monsters have already left the field. A single Pendulum Summon of five monsters would meet it in one go.

Skill Drain: negated, but still activated

Skill Drain negates the effects of all face-up monsters while they are face-up on the field, but those monsters can still activate their effects; costs are paid as usual and the effect is negated. Its text: "Activate this card by paying 1000 LP. Negate the effects of all face-up monsters while they are face-up on the field (but their effects can still be activated)." It is a Continuous Trap, so its negation lasts as long as it stays face-up on the field (p. 30).

• The 1000 LP is the activation cost, paid before it goes on the chain (glossary, p. 54).
• Monsters in the hand, Graveyard or banishment aren't face-up on the field, so the text doesn't cover their effects.
• Activations still happen, so cards that react to an activation still see them.
• If Skill Drain leaves the field or is negated, the monsters' effects apply again.

Forbidden Droplet: costs and response limits

Forbidden Droplet sends any number of your other cards to the Graveyard as its cost, then at resolution chooses that many of your opponent's Effect Monsters, halving their ATK and negating their effects until the end of the turn; your opponent can't respond to it with cards of the same original type (Monster, Spell or Trap) as the cards you sent. Its text: "Send any number of other cards from your hand and/or field to the GY; choose that many Effect Monsters your opponent controls, and until the end of this turn, their ATK is halved, also their effects are negated. In response to this card's activation, your opponent cannot activate cards, or the effects of cards, with the same original type (Monster/Spell/Trap) as the cards sent to the GY to activate this card. You can only activate 1 'Forbidden Droplet' per turn."

• It is a Quick-Play Spell. From the hand, only in your own turn; Set, it can be used from your opponent's next turn (p. 29).
• The monsters are chosen, not targeted, and the choice happens at resolution (see target vs choose).
• Send a Monster and a Trap, and your opponent can't respond with monster effects or Traps, but could still respond with a Spell.
• The restriction applies only "in response to this card's activation", meaning the link directly above it.
• Halving ATK and negating effects aren't destruction.

PSY-Framegear Gamma: empty field and PSY-Frame Driver

Gamma can be activated only when your opponent activates a monster effect while you control no monsters; it Special Summons itself from your hand together with PSY-Frame Driver from your hand, Deck or Graveyard, then negates that activation and destroys that monster. Its text: "Cannot be Normal Summoned/Set. Must be Special Summoned by card effect. Once per Chain, when your opponent activates a monster effect while you control no monsters (Quick Effect): You can Special Summon both this card from your hand and 1 'PSY-Frame Driver' from your hand, Deck, or GY, and if you do, negate that activation, and if you do that, destroy that monster. During the End Phase, banish the face-up monsters Special Summoned by this effect."

• "While you control no monsters" is a condition for activation. Spells and Traps on your field don't matter.
• It needs Driver: the effect Summons both cards together, and "and if you do" ties the negation to that Summon. With no Driver in your hand, Deck or Graveyard, there is nothing to resolve.
• It responds only to monster effects, not to Spell or Trap Cards.
• The two monsters are banished during the End Phase, not right away.

Super Polymerization: materials and no responses

Super Polymerization discards a card as its cost, then Fusion Summons using monsters from either field, and neither player can activate cards or effects in response to its activation. Its text: "Discard 1 card; Fusion Summon 1 Fusion Monster from your Extra Deck, using monsters from either field. Neither player can activate cards or effects in response to this card's activation."

• It is a Quick-Play Spell, so the Set rules on page 29 apply.
• "Either field" means the monsters on the field of either player, not the hand or the Graveyard.
• The discard is paid at activation and isn't refunded.
• The no-response clause protects only the activation. Continuous effects already on the field still apply, and it doesn't make an illegal Fusion legal: you still need materials that match the Fusion Monster.

Cards and effects not covered here

We left out the difference between "Once per turn" and "You can only use this effect of [card name] once per turn". The second wording names the card, so it limits every copy with that name, but Konami's rulebook doesn't explain the first one, and we didn't want to state a rule we couldn't source. If a specific interaction isn't listed here, Konami's official card database shows the current text, and a judge at your event has the final word.

FAQ

Can you Flip Summon and Normal Summon in the same turn?

Yes. A Flip Summon doesn't use your once-per-turn Normal Summon, so you can flip a monster Set on an earlier turn and still Normal Summon or Set another one.

Does a Flip Summon count as a Normal Summon?

No. It is a separate way of Summoning a monster that is already face-down on your field, with no turn limit, and it counts as that monster's change of battle position for the turn.

Can Tokens be used for an Xyz Summon?

Never. The rulebook says Tokens can't be Xyz Material, whatever their Level.

Can Tokens be used for a Synchro Summon?

Yes, if the Token has a Level that fits and neither the card that created it nor the Synchro Monster forbids it. Some Token makers do forbid it in their own text.

Do Pendulum Monsters go to the Graveyard?

Not from the field. A Pendulum Monster Card that would go from the field to the Graveyard is placed face-up in the Extra Deck instead. From the hand or Deck, it can go to the Graveyard normally.

Can I respond to a Summon?

Not with a chain. Summoning isn't an activation, so you respond to the effects that trigger after it, or use a card that specifically negates a Summon.
