Rulings for Coordemon

Official clarifications published for this card.

If a card is affected by "can't activate [When Digivolving] effects," can I process just the "by" condition in its [When Digivolving] effect?

No, you can't.

25 December 2025

A card that was given "can't activate [When Digivolving] effects" digivolved into a card that has a [When Digivolving] [When Attacking] [Once Per Turn] effect. Does that count as an instance of that effect's [X Per Turn] even if that effect can't be activated upon the timing when that card digivolved?

No, it doesn't count. The effect can't activate upon the [When Digivolving] timing, therefore it doesn't count as an instance of that effect's [X Per Turn].

25 December 2025

What does "[When Digivolving] effects don't activate" mean, exactly?

This effect prevents [When Digivolving] effects on cards from activating. [When Digivolving] effects can no longer activate by triggering or when effects such as "activate that card's [When Digivolving]" effect" activate.

I used a card affected by "can't activate [When Digivolving] effects" to attack. Can I activate that card's [When Digivolving] [When Attacking] effect at such times?
