Digimon inherited effects: which text is active?
On this page
A Digimon uses the main text of its top card and the inherited effects of the cards below. It does not have all the main effects of each stage. To read a stack correctly, separate the main area from the inherited effect box and check the conditions of each ability that is actually available.
What part of each card you should read
The top card represents the current Digimon: it determines its characteristics and provides its main effects. The cards below are its digivolution cards. The inherited-effect box from these sources can give abilities to the Digimon that contains them. The main text of one source does not become inherited because you placed it under another card.
Imagine a pile with a top card that has an attacking ability and a lower source whose inherited box increases DP under certain conditions. Both texts are available to the Digimon. However, if that source also had a main When Digivolving ability, it does not reactivate it every time the upper Digimon attacks. The position and printing area decide which text you consult.
A stack is not a hand of interchangeable abilities
You cannot freely rearrange the lower cards to choose which stage is left above. Their order is part of the state of play and only changes when a rule or an effect allows it. Keep a sufficient portion of each card visible to recognize its inherited effects without disassembling the stack. If you need to examine it, keep the order when returning it to the table.
To practice, take a stack of four cards and write two columns: main text available and inherited texts available. In the first there will normally be a card. In the second you will include only the lower boxes that give something to Digimon. This reading avoids attributing to it a spectacular effect that belongs to a stage that ceased to be the top card.
Having an effect does not amount to meeting its condition
An inherited effect may depend on attacking, on a trait of the Digimon, an amount of cards in your pile or from another state. Read the whole condition and then the consequence. Seeing the box on the table doesn't guarantee that its benefit is working. You must also respect temporary restrictions, like once per turn, when they appear.
Suppose one source grants DP only during your turn and another grants it while the Digimon fulfills a specific trait. To calculate DP on the rival turn, the first may not contribute and the second depends on the current trait of the top card. Record the origin of each modifier; adding all visible numbers without conditions produces a total that can be incorrect on both turns.
Who possesses the inherited ability
The inherited ability is granted to the Digimon containing the source. It is not functioning as an independent ability of a loose card under the stack. The rules provide for this concession even if the source belongs to a category other than Digimon. The decisive thing is that the effect and the rules allow that card to act as a source and grant the text.
This distinction matters when another ability refers to the effects of a Digimon. Do not discard an inherited effect simply because its original source has another type. At the same time, pay attention to a formulation that expressly mentions ‘this card’: there are specific provisions for references to the source itself. In a dubious interaction, present the two complete cards to the judge instead of summarizing them as "a bottom-up effect".
What happens when you digievolve
When you digievolve, the previous top card goes under the new one. Its main text is no longer the main text of the Digimon and its inherited box may be available. The other sources are not automatically replaced. Evolution changes the visible part of the stack and can change its characteristics, conditions and abilities.
For example, an inherited ability that requires a trait may fail to bring its benefit if the new top card no longer fulfills it. Another one that did not have a trait condition may still be available. Check for active effects after evolution, before announcing the next attack. It is easier to correct a calculation at that time than to rebuild a battle that used incorrect DP.
Once per turn and stage changes
Digivolving is not a general permission to re-use everything that has already been activated. The rules retain states of inherited effects when changing stages when appropriate. Identify what ability the restriction had and whether the Digimon already used it. Do not interpret a new top illustration as an automatic turn restart for all sources.
You can place a marker next to the stack for each limited effect that has been used and remove it when applicable according to the rule. If there are two sources with similar texts, record which one was activated. The marker does not need to cover the card: its function is to remember a public fact. In competitive games, a clear note saves discussions on whether evolution allowed a second activation.
The breeding area has its own rules
Don't move all the interactions from the battle area to the breeding area. The rules limit the effects that apply there. A breeding stack may show inherited boxes, but that alone does not authorize you to use your abilities as if the Digimon were attacking or staying in the battle area. Check any express exceptions in the card.
By moving the Digimon to the battle area, you reread the conditions in your new situation. The benefit that was not applied in breeding may be relevant there, and an effect that requires concrete action still needs such action to occur. To learn, physically separate both areas and announce movement; so you don't confuse preparing a stack with activating effects during preparation.
Removing a source changes the reading
If an effect removes a lower card, the Digimon ceases to obtain the effect inherited from that source. If you remove the top card by De-Digivolve, the exposed card goes on to determine the current identity and you need to check which texts are left above and below. They are not equivalent operations: one removes a particular source and the other can change the visible stage.
In a stack with three bonuses, removing a single source can reduce only one of them, but also alter a condition based on the number of lower cards. Recalculate from the resulting state. Do not mechanically subtract a figure if that deletion causes another box to fail to meet its requirement. The correct calculation depends on the entire stack that remains.
Learn a deck without memorizing each paragraph
Organize your deck sources by function: DP, draw, memory, protection, or attack triggers. Then write down what condition limits each group. This reference sheet is used to study, but during a game the current text of the cards takes precedence. Avoid abbreviations such as "always memory" when in reality it requires a specific circumstance.
To buy a card you want to use as a source, check its identifier and the inherited-effect box of that printing. Sharing character or level does not guarantee sharing ability. If you already have a copy, photographing the lower area next to the card number makes it easy to compare versions without confusing alternative art with a different text. The need for play is decided by identity and effect, not by illustration.
Record the source of each bonus
In a stack with several sources, identify which card grants each inherited benefit and the condition it requires. When a source is removed, stop counting the effects dependent on that source. Do not automatically erase a separate bonus from the top card. When the top card changes, recheck trait, turn and state conditions used by the remaining sources.
For practice, calculate DP immediately before attacking and again after a relevant state change. Explain each addition by naming its source. This is initially slower, but it quickly reveals whether you were reading the main effect of a lower card or retaining a bonus whose condition no longer applies.
Frequently asked questions
Does the top card use its own inherited effect?
Not simply because it is on top. This box serves to give effect when the card is under the appropriate Digimon; above, you consult its main text and the effects that other sources give it.
Can I use the main effect of a lower card?
Not as a general rule. Being under another card does not transform its main text into an inherited effect. You would need a specific provision to allow such interaction.
Does digivolving reset all effects once per turn?
No. The top card change does not grant a general restart. Keep track of the abilities used and check the rules of the specific ability.
