Q&A
Date
Question

If I use this card's [On Play] [When Digivolving] effect to digivolve a Digimon in the breeding area, does that Digimon's [When Digivolving] effect trigger?

Answer

No, it doesn't trigger.

Date
Question

What order do a [Security] effect, "when [...] performs a security check" effect, and "when a card is removed from [...] security stack" effect activate when they trigger simultaneously upon a security check?

Answer

[Security] effects take precedence for activation.

Upon a security check, a [Security] effect will immediately activate without pending activation.

For other triggered effects, the turn player activates their effects first.

Date
Question

If an opponent's Digimon is attacking and another effect digivolves one of my Digimon into this card, does that meet the "if during an attack" condition in this card's [On Play] [When Digivolving] effect?Jun. 25, 2025 Updated

Answer

Yes, it does.
