Q&A
Date
Question

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

Answer

This effect prevents [When Digivolving] effects on cards from activating.

Date
Question

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?

Answer

Yes, you can.

The effect can activate if it's triggered upon the [When Attacking] timing.

Date
Question

If a card is affected by "can't activate [When Digivolving] effects," can it activate its own [When Digivolving] effect using an effect such as "activate 1 of that card's [When Digivolving] effects"?

Answer

No, it can't be activated.

Date
Question

If a card is affected by "can't activate [When Digivolving] effects," can it activate another card's [When Digivolving] effect using an effect such as "activate 1 of that card's [When Digivolving] effects as an effect of this card"?

Answer

No, it can't be activated.

Date
Question

Can I use "activate 1 of that card's [When Digivolving] effects as an effect of this card" on a card that isn't affected by "can't activate [When Digivolving] effects" to activate the [When Digivolving] effect on another card that's affected by "can't activate [When Digivolving] effects"?

Answer

Yes, you can.

Date
Question

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

Answer

No, you can't.

Date
Question

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?

Answer

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].
