Pokémon TCG special card mechanics: Prism Star, Lost Zone, ACE SPEC and more

Pokémon's special cards come with their own limits: one ACE SPEC card in your whole deck, one Radiant Pokémon, one copy of each Prism Star card by name, one GX attack and one VSTAR Power per game, and anything sent to the Lost Zone stays there for the rest of the game. In the 2026 Standard format only cards with regulation mark H, I or J are legal, so most of these mechanics now live in Expanded or in casual play. Each mechanic gets its own section below, checked against the official rulebook dated September 2026 and the Tournament Handbook revised on 1 September 2026.

Core rules such as setup, evolving, attaching Energy and Special Conditions are not repeated here. This page covers what changes when a card has a rule box, a symbol or a special category, and what that means for deckbuilding and collecting.

If all you need mid-game is a reminder of what one of these mechanics does, the keyword glossary sums it up in a sentence and links back to its section of this guide.

At a glance: which mechanic, which era, where it is legal

Regulation marks: which cards are Standard legal in 2026

In the 2026 Standard format, cards with regulation mark H, I or J are legal (plus any newer marks released before the next rotation); G-mark cards left Standard on 10 April 2026 for in-person events and on 26 March 2026 on Pokémon TCG Live. The regulation mark is the small letter printed at the bottom of the card. The official rotation announcement of 9 January 2026 says legality is no longer based on the expansion a card comes from, only on that letter. Checked on 21 October 2026.

The Tournament Handbook table

Section 4.1.1 of the Tournament Handbook (revised 1 September 2026) lists the marks as follows:

Expanded also includes every Black & White, XY and Sun & Moon expansion, a few standalone products such as the Trainer Kits, the McDonald's Collections 2011–2021 and Detective Pikachu, and some Black Star promos. The 2026 announcement confirms Expanded is unchanged: Black & White onwards.

The diagram puts the table on a single line: which letters are legal in each format, since when, and where the 2026 rotation falls.

Reprints: when an older copy still counts

A card with no mark, or with a rotated mark, can still be played if a currently legal version exists with an identical name and functionally identical text (Handbook section 4.1.3). The announcement gives two examples. Rare Candy from Sun & Moon is still usable because the Mega Evolution printing carries an I mark, and Boss's Orders from Rebel Clash, which has a D mark, is usable because the Mega Evolution Boss's Orders is marked I too. Similar wording is not enough, though: the Handbook explains that "put 1 damage counter" and "does 10 damage" are different mechanics, which is why two Rainbow Energy cards from different eras aren't interchangeable.

When a brand-new card becomes legal

New cards become legal on the second Friday after their US release (section 4.1.2). For staggered releases, the clock starts two weeks after the first of the Booster Display, Booster Bundle or sleeved booster to hit shelves. Promos have their own schedule, covered in the promo section below.

Release dates for upcoming expansions are in the release calendar. It lists the dates for Spain and Europe; for this rule the US release is what counts, so double-check it when the two differ.

Worked example: checking a deck before a Standard event

1. Pull out the H, I and J cards. They pass the mark check as they are.
2. For every G, D, E or F card, look for a reprint with the same name, an H, I or J mark and identical text. If there is one, your old copy is fine. If not, it comes out.
3. Check the language: at Championship Series events in the Europe rating zone, English, French, German, Italian, Portuguese and Spanish cards are legal (section 2.3.1).

To check a single card without hunting for its image, the format legality checker reads its regulation mark and applies this same Handbook table. Step 2 is still on you: if your copy has an old mark, look for the reprint before you set it aside.

Common mistakes

• Going by the set's release year. A 2026 product can contain reprints with different marks.
• Treating rotated cards as dead. They are still legal in Expanded and fine for casual games.
• Mixing up the regulation mark with the set code or the rarity symbol.

Prism Star cards: the ◇ symbol and the one-per-name limit

A Prism Star card has a ◇ symbol after its name and two rules: you can't have more than one card with that name in your deck, and if it would go to the discard pile, it goes to the Lost Zone instead. The limit is per name, not per category. The rulebook's own example is a deck running one Giratina ◇, one Lunala ◇, one Cyrus ◇ and one Super Boost Energy ◇ together. That is the big difference from ACE SPEC cards, where you get one in total.

Prism Star cards can be Pokémon, Trainer cards or Special Energy (rulebook glossary). They come from the Sun & Moon series: Cyrus ◇ and Super Boost Energy ◇, for instance, are from Ultra Prism. All of Sun & Moon is Expanded legal and outside Standard.

Reading the rule on the card

The official text of Cyrus ◇ (Ultra Prism 120/138) reads "You can't have more than 1 ◇ card with the same name in your deck. If a ◇ card would go to the discard pile, put it in the Lost Zone instead." Its Supporter effect follows, with its own condition for playing it. The Prism Star rule stays with the card wherever it is.

When "goes to the Lost Zone" kicks in

• You play Cyrus ◇. A Supporter normally goes to the discard pile after use, so this one goes to the Lost Zone.
• A ◇ Pokémon is Knocked Out. The Pokémon goes to the Lost Zone, while ordinary attached cards still go to the discard pile.
• You discard Super Boost Energy ◇ to retreat or for an attack cost. It ends up in the Lost Zone too.
• An effect that returns it to your hand or shuffles it into your deck doesn't send it to the discard pile, so the rule doesn't apply.

Common mistakes

• Running two copies of the same name because the artwork or card number differs.
• Assuming the limit is one Prism Star card in total, as with ACE SPEC.
• Leaving a Knocked Out ◇ Pokémon in the discard pile, where it could later be recovered by mistake.

The Lost Zone: what it is, where it goes and what you can get back

The Lost Zone is considered out of play: cards sent there can't be recovered or played again for the rest of that game, and you put them face up anywhere out of play. So there is no fixed spot for it on the playmat. The rulebook only asks for the cards to be face up and outside the play area, which in practice means a pile kept clearly apart from your discard pile where both players can see it.

Cards reach the Lost Zone because an attack, Ability or Trainer card says so, or through the Prism Star rule. You never get to choose the Lost Zone instead of the discard pile, or the other way round: the card text decides.

Discard pile vs Lost Zone

At tournaments the Lost Zone does have a place: section 6.1.2 of the Tournament Handbook asks you to keep it directly above your Prize cards, neatly stacked so it doesn't interfere with other cards. The diagram brings both together: where a card goes and where each pile sits on the table.

Example: Comfey from Lost Origin

Comfey's Flower Selecting Ability (Lost Origin 79/196) reads "Once during your turn, if this Pokémon is in the Active Spot, you may look at the top 2 cards of your deck and put 1 of them into your hand. Put the other card in the Lost Zone." Reveal Rare Candy and an Energy, keep the Rare Candy, and that Energy is gone for good, even if you later play a card that gets Energy back from the discard pile. Before you use it, decide which card you can afford to lose if both turn out to be useful.

The Lost Zone in 2026

Pokémon's official Lost Origin page built that expansion around the Lost Zone, with Giratina VSTAR on the front. Lost Origin cards carry the F mark (the official image of Comfey 79/196 shows it), and F left Standard in April 2025. The rule is still in the 2026 rulebook because any new card can use it, but Lost Zone decks are an Expanded thing today.

Common mistakes

• Stacking the Lost Zone on top of the discard pile. Sooner or later the piles get mixed and a card comes back that shouldn't.
• Placing the cards face down. The rulebook says face up.
• Thinking a card that counts your Lost Zone lets you take something out. Counting isn't recovering.

ACE SPEC: how many you can run in a deck

You can include only one ACE SPEC card in your entire deck, not one of each name and not one of each card type. The rulebook puts it plainly: "your deck can include only one total ACE SPEC card." An ACE SPEC Item and an ACE SPEC Energy compete for the same single slot.

ACE SPEC cards were introduced in the Black & White series and came back in Scarlet & Violet. Prime Catcher, Temporal Forces 157/162, is one from the newer run: it switches one of your opponent's Benched Pokémon into the Active Spot and, if you do, lets you switch your own Active Pokémon too.

How it fits with the other deckbuilding rules

• The usual four-copies-per-name rule doesn't raise the cap. For ACE SPEC the maximum is one, full stop.
• Your 60-card deck includes the cards that end up as Prizes. If your ACE SPEC is prized, it is still your one ACE SPEC.
• The limit applies when building. Once drawn, the card follows the rules of its type: an Item plays as an Item, a Tool as a Tool.
• Prism Star cards don't count as ACE SPEC. In Expanded you could run several differently named ◇ cards and an ACE SPEC as well.

Worked example

Your list already has one Prime Catcher and you want to add an ACE SPEC Energy. You can't, because that would make two. You have to pick one. Since a single copy in 60 cards won't show up every game, the rest of the list should still work on the turns you don't draw it.

The numbers for a single copy in 60 cards are easy to work out: it will be in your 7-card opening hand in 11.7% of games (7 in 60) and among your 6 Prize cards in 10% (6 in 60). That is the hypergeometric distribution with one copy, ignoring mulligans. For other copy counts, use the opening hand calculator and the Prize card odds tool.

In Standard 2026

Scarlet & Violet and Mega Evolution era ACE SPEC cards are legal if their mark is H, I or J. The Black & White ones are Expanded only.

Ancient Traits: not Abilities and not attacks

An Ancient Trait is a special power printed just under the Pokémon's name, such as Ω Barrier or α Recovery; it is neither an attack nor an Ability, so cards that stop attacks or Abilities don't affect it. Ancient Traits first appeared in XY—Primal Clash, which the official expansion page dates to 4 February 2015.

How to read them

• Look under the name, not in the attack box. The same card can have an Ancient Trait plus an Ability or normal attacks.
• Read the whole trait. The rulebook only says they grant "special powers"; what each one does is in its text.
• If your opponent plays something that shuts off Abilities, the trait keeps working. If an effect blocks something broader, such as all "effects" of a Pokémon, read both cards carefully, because the basic rulebook doesn't settle that case.

Era and format

Ancient Traits belong to the XY series, which is Expanded legal. Don't confuse them with the "Ancient" label from Scarlet & Violet—Paradox Rift: that label marks a card as Ancient or Future and is covered in a separate appendix of the rulebook.

GX attacks and TAG TEAM: one per game

Each player can use at most one GX attack during an entire game, however many Pokémon-GX they play; when you use it, turn your GX marker face down. The limit belongs to the player, not to the card, so retreating, evolving or bringing in another Pokémon-GX doesn't give it back. A Pokémon-GX that is Knocked Out gives up 2 Prize cards.

What else to know

• GX is part of the name, so you can run 4 Incineroar and 4 Incineroar-GX.
• Pokémon-GX use the normal Evolution stages. Primarina-GX evolves from Brionne just like Primarina, and a Basic Pokémon-GX can be your starting Active Pokémon.
• A TAG TEAM is a Basic Pokémon-GX that gives up 3 Prize cards. Its GX attack gets a bonus effect if you meet a requirement.
• Ultra Beasts are Pokémon-GX with crimson colouring and a label in the upper-right corner.

Example: Pikachu & Zekrom-GX

Its Tag Bolt-GX attack does 200 damage, and if the Pokémon has at least 3 extra Lightning Energy attached beyond the cost, it also does 170 damage to one of your opponent's Benched Pokémon. Use it without the extra Energy and you have spent your only GX attack of the game without the bonus, so pick the turn deliberately.

Era and format

Pokémon-GX come from the Sun & Moon series, which is Expanded today. A GX attack has nothing to do with a VSTAR Power: each has its own marker and its own limit.

VSTAR Power: once per game, Ability or attack

You can use only one VSTAR Power in the whole game, no matter how many Pokémon VSTAR you play; a VSTAR Power can be an Ability or an attack, and using either one uses up both. Flip your VSTAR marker once you've used it. A Pokémon VSTAR that is Knocked Out gives up 2 Prize cards.

How it works

• VSTAR is its own Evolution stage. Arceus VSTAR evolves only from Arceus V, never from a regular Arceus.
• Pokémon VSTAR still count as Pokémon V, so anything that affects Pokémon V affects them.
• An Ability-type VSTAR Power isn't an attack, so using it doesn't end your turn unless its text says so.

Example: Arceus VSTAR

Arceus VSTAR (Brilliant Stars 123/172) has the VSTAR Power Starbirth: "During your turn, you may search your deck for up to 2 cards and put them into your hand." Use it on your first turn with Arceus and you can't use any other VSTAR Power for the rest of the game, even if you later bench a different VSTAR with a VSTAR Power attack.

Era and format

Pokémon VSTAR come from Sword & Shield. The official image of the Brilliant Stars Arceus VSTAR shows an F mark, so it has been out of Standard since April 2025. The 2026 30th Celebration expansion reprints Arceus VSTAR in its Classic Collection (27/30). We found no official statement on that reprint's tournament legality, so ask the organiser before bringing it.

Radiant Pokémon: one per deck

You can have only one Radiant Pokémon in your deck in total, so Radiant Greninja and Radiant Charizard together already break the limit. You can spot them by the word Radiant in the name, their special Shiny colouring and the "Radiant Pokémon Rule" box.

Rules that come with them

• "Radiant" is part of the name, so 4 Greninja and 1 Radiant Greninja is fine.
• They are always Basic Pokémon and don't evolve from or into anything.
• They count as Pokémon with a Rule Box, so cards that mention those Pokémon affect them.
• The limit is a deckbuilding rule. There is no marker and no once-per-game restriction.

Example and format

Radiant Greninja (Astral Radiance 46/189) has the Concealed Cards Ability: discard an Energy card from your hand to draw 2 cards, once during your turn. Its official image shows an F mark, and Pokémon's Lost Origin page announced three new Radiant Pokémon in that set. Check each Radiant's letter; the one we checked is Expanded only.

Pokémon ex, Tera ex and Pokémon-EX: not the same card

When a Pokémon ex is Knocked Out, your opponent takes 2 Prize cards; the older Pokémon-EX (capital letters, with a hyphen) also give up 2 but are a different name from a different era, and Mega Evolution Pokémon ex give up 3. That is why you can run 4 Magnezone ex and 4 Magnezone-EX in the same deck: the rulebook treats them as different names.

Tera Pokémon ex

On top of giving up 2 Prizes, a Tera Pokémon ex takes no damage from attacks while it is on your Bench. That protection covers your own attacks as well as your opponent's. Damage counters placed by other effects are a separate matter and depend on each card's wording.

Counting Prizes correctly

Look at the rule box on the top card of the Pokémon that was just Knocked Out. The stages underneath and any attached cards don't add Prizes. If you have 2 Prize cards left and Knock Out one of your opponent's Pokémon ex, you take both and win.

Mega Evolution: 2025–2026 ex vs XY-era -EX

Today's Mega Evolution Pokémon ex give up 3 Prize cards and have no other special rules; the XY-era Mega Evolution Pokémon-EX gave up 2 Prizes and ended your turn as soon as you Mega Evolved. They share the word "Mega" but work differently and can't be mixed in the same Evolution line.

Mega Evolution Pokémon ex (Mega Evolution series)

• They can be Basic, Stage 1 or Stage 2 and follow the normal Evolution rules, with one twist: they evolve from whatever the card says. Mega Lucario ex (Mega Evolution 77/132, 340 HP) evolves from Riolu, not from Lucario or Lucario ex. Mega Gardevoir ex evolves straight from Kirlia, and Mega Kangaskhan ex is played as a Basic Pokémon.
• They count as Pokémon ex, so a card that searches for "a Pokémon ex" can find one.
• Evolving into one doesn't end your turn.

Mega Evolution Pokémon-EX (XY)

• They are a stage called MEGA that evolves from the Pokémon-EX: M Venusaur-EX evolves only from Venusaur-EX.
• When one of your Pokémon becomes a Mega Evolution Pokémon-EX, your turn ends, so do everything else first.
• Primal Reversion Pokémon-EX work the same way. The official Primal Groudon-EX entry (Primal Clash 86/160) carries the rule that your turn ends when one of your Pokémon becomes Primal Groudon-EX.

The three special evolutions that get mixed up most, side by side: what they evolve from, how many Prizes they give up and what limit they bring.

Example: when to put a Mega ex in the Active Spot

Your opponent has 3 Prize cards left. If they Knock Out your Active Mega Lucario ex, they win on the spot. If your Active Pokémon gives up only 1 Prize, they would still need 2 more. Count your opponent's remaining Prizes before you promote it.

Pokémon V-UNION: four pieces from the discard pile

You play a Pokémon V-UNION by putting all four of its pieces onto your Bench at once from your discard pile, during your turn and only once per game for each name; it takes one Bench spot and gives up 3 Prize cards. You can't play a single piece, and it can't go into play during setup because it isn't a Basic Pokémon.

• All four pieces share one name (for example, Mewtwo V-UNION), so your deck can hold four cards with that name in total, not four of each piece. All four must come from the same set and be by the same artist.
• Outside of play each piece is a separate card. A search for "a Pokémon" gets you one piece.
• A single piece only has a type, a category and a name. A search for a Pokémon with a Retreat Cost of 3 or more finds no piece at all.
• It is neither Basic nor Evolution: effects on "Basic" Pokémon don't touch it, but effects on unevolved Pokémon do.
• In play it counts as a Pokémon V with a Rule Box and can hold only one Pokémon Tool.

The official Greninja V-UNION card sums it up in its header: once per game during your turn, combine 4 different Greninja V-UNION from your discard pile and put them onto your Bench. These cards date from the Sword & Shield era (2021), before marks H, I and J existed.

BREAK Evolution: what a Pokémon BREAK keeps

A Pokémon BREAK keeps the attacks, Abilities, Weakness, Resistance and Retreat Cost of its previous Evolution and adds the new attacks or Abilities on the BREAK card; its HP changes and it can even change type. BREAK is part of the name (Raichu and Raichu BREAK are different names) and it is its own stage that counts as an Evolution card, so the normal Evolution rules apply.

In practice, read the sideways BREAK card together with the card underneath. The only things that change are what the BREAK card replaces: HP and, sometimes, type. The XY expansions that introduced them, BREAKthrough and BREAKpoint, are on the Handbook's Expanded list.

Pokémon LEGEND: two halves played together

A Pokémon LEGEND is made of two cards, and you can only put it onto your Bench from your hand with both halves at the same time. The official Ho-Oh LEGEND entry (HeartGold & SoulSilver 112/123) says you put this card from your hand onto your Bench only with the other half of Ho-Oh LEGEND. One half on its own can't be played.

For collecting, log each half separately: two top halves don't make a Pokémon. The HeartGold & SoulSilver sets predate Black & White, so they are not in Expanded and only see play in Unlimited or casual games. The 30th Celebration Classic Collection includes Darkrai & Cresselia LEGEND (19/30 and 20/30); we found no official word on their tournament legality.

Fossils: Trainer cards that play as Basic Pokémon

Rare Fossil, Unidentified Fossil and the Fossils with "Antique" in their name are Item cards that can be played as Basic Pokémon; in your hand, deck or discard pile they don't count as Basic Pokémon. That is why a card that searches your deck for "a Basic Pokémon" can't find them, even though once in play they take up a Bench spot.

• Rare Fossil and Unidentified Fossil evolve into any Pokémon that says "Evolves from Rare Fossil" or "Evolves from Unidentified Fossil".
• Antique Fossils name what they evolve into: Antique Helix Fossil says "Evolves into Omanyte".
• Restored Pokémon, such as the Kabuto from XY—Fates Collide, are different again. They are neither Basic nor Evolution cards and only reach the Bench through the effect of their Fossil Item card.
• With older Fossil cards, the "Evolves from" or "Put this card into play" line on each card is what counts.

Legality depends on the individual card, since Fossils have been printed in several eras. Check its mark or its set.

Black Star Promos: SWSH, SVP and MEP

Black Star Promos are identified by their series prefix plus number (such as SVP 001 or MEP 012), and for Standard you check them like any other card: by regulation mark. The prefix changes with each series: SWSH for Sword & Shield, SVP for Scarlet & Violet and MEP for Mega Evolution. That is why "promo 001" identifies nothing on its own: SVP 001 is Sprigatito, while MEP 001 is Meganium.

What the Tournament Handbook says

• BW promos 01 and up, XY promos 01 and up and SM promos 158 and up are legal in Expanded, not in Standard (section 4.1.1).
• Promos from special collections become legal on the first or third Friday of the month after release, according to the official Promo Card Legality Status page, which is updated monthly. As of 21 October 2026, that page lists 20 November 2026 for several upcoming MEP promos (MEP 111 to MEP 117, with two marked "Upon Release").
• In Unlimited, every promo released in the United States is legal.

Cataloguing a promo

Always record the prefix and the number together, as text. If a spreadsheet turns "001" into "1", keep the full code in a separate column. An event or product stamp on an expansion card doesn't make it a Black Star Promo: it keeps its expansion number.

Jumbo cards: for display, not for play

Jumbo cards, which Pokémon's product pages call "oversize" cards, come in some collections next to the same promo in normal size, and only the normal-size card is playable. The Mega Greninja ex Premium Collection, for example, contains a foil Mega Greninja ex promo and an "oversize lenticular promo card" of the same Pokémon. The official listing describes them as the playable and the display sizes.

The Tournament Handbook doesn't mention oversize cards, but it requires every sleeve in a deck to be the same size and to enclose a single card entirely (section 2.2), which a jumbo card can't do alongside standard cards. When buying or trading, say "standard copy" or "oversize copy" and ask for a photo with a ruler next to it, because sizes vary between products. For storage ideas, see the sleeves, binders and storage guide.

World Championships decks: official replicas that aren't tournament legal

Cards from the World Championships decks are not legal for tournament play: they have different card backs from normal Pokémon cards, silver borders and the player's signature on every card. That is stated on the official page for the 2025 World Championships decks, on sale from 19 June 2026, which presents them as card-for-card replicas of real contender decks for learning how they play.

To take one of those lists to an event, you need the regular printings of the same cards. The Handbook requires genuine, unmarked cards with consistent backs, and even treats Japanese cards as "marked" because of their different backs (section 2.1). An opaque sleeve doesn't change that. For a collection, log them as a separate product with the World Championships year and the player's name.

Finding the cards you're missing

If you're short of a particular ACE SPEC or one half of a LEGEND, TradeMatches lets you keep a list of what you have and what you want, see matching collectors nearby and chat with players in your province. Before an event, it's also worth reading how to prepare for your first TCG event and the card language and edition guide.

FAQ

How many ACE SPEC cards can you have in a Pokémon deck?

One in total. It makes no difference whether the names or card types differ: an ACE SPEC Item, Tool or Energy all share that single slot.

Can I run more than one Prism Star card?

Yes, as long as each has a different name. What you can't do is include two ◇ cards with the same name. Bear in mind they are Expanded only now.

Where in the play area should the Lost Zone be located?

Anywhere out of play, with the cards face up. The tidy option is its own pile, away from your discard pile and visible to both players.

Does an Ability-blocking card stop an Ancient Trait?

No. The rulebook is explicit that Ancient Traits are not attacks or Abilities, so those blockers don't touch them.

If I use a GX attack, can I still use a VSTAR Power later?

Yes. They are separate limits, one per game each. In practice that only comes up in Expanded or Unlimited games.

Which regulation marks are legal in Standard right now?

H, I and J, as of 21 October 2026. G left Standard on 10 April 2026 for in-person events.
