Q&A
Date
Question

What does "may battle" mean, exactly?

Answer

This effect directly performs a battle.

If this effect is activated, the chosen Digimon battle, as with the standard rules.

Date
Question

If 2 Digimon including a Digimon that has an "effects don't affect" effect are chosen for a "may battle" effect, can those Digimon battle?

Answer

Yes, they can battle.

A card that has an "effects don't affect" effect can still be chosen for an effect. In addition, a battle itself is a rule that compares DP, not an effect. Therefore, a Digimon that isn't affected by effects can be chosen, and then it can battle.

If it loses the battle, it will be deleted as normal according to the rules.

Date
Question

During an attack by my Digimon with <Piercing>, I activate this card's [On Play] [When Digivolving] [When Attacking] effect, the attacking Digimon and an opponent's Digimon battle, and my opponent's Digimon was deleted in battle.

Then, if the attack target successfully becomes an opponent's Digimon and it's also deleted in battle, do I use that Digimon's <Piercing> to perform 2 checks?

Answer

No, you only perform 1 security check for <Piercing>.

Only 1 security check can be performed during a single attack, even if <Piercing> activates multiple times.

However, if the number of checks is modified by <Security A.>, that number of cards will be checked in a single security check.

Date
Question

During an attack by my Digimon with <Piercing>, I use this card's [On Play] [When Digivolving] [When Attacking] effect to have that Digimon and an opponent's Digimon battle, and my opponent's Digimon was deleted in battle.

Then, if the attack target successfully becomes an opponent's Digimon, it loses the battle, but an effect prevents it from being deleted, can I still activate that Digimon's <Piercing>?

Answer

Yes, you can.

<Piercing> is an effect that triggers and activates if an opponent's Digimon is deleted in battle during the attack, and it's processed immediately before the end of attack timing.

<Piercing> will still trigger if the Digimon with <Piercing> successfully attacks a Digimon, even if another battle occurs during this battle.

Date
Question

When does "when this Digimon wins a battle" trigger?

Answer

It triggers when the battle is won.

When the Digimon with this effect wins a battle, the opponent's Digimon that lost the battle is deleted, then the "when this Digimon wins a battle" effect can be activated.

Date
Question

Does a "when this Digimon wins a battle" effect also trigger when a battle against a Security Digimon is won?

Answer

Yes, it triggers.

Date
Question

A Digimon with a "when this Digimon wins a battle" effect won a battle, and the opponent's Digimon that lost the battle is deleted.

At such times, in what order can players activate the "when this Digimon wins a battle" effect and the effects that trigger upon the losing Digimon being deleted?

Answer

They trigger simultaneously, so the turn player can activate their effects first.

Date
Question

A Digimon with a "when this Digimon wins a battle" effect won a battle, and the opponent's Digimon lost the battle.
