Q&A
Date
Question

Can I choose to not delete any of my opponent's Digimon by not choosing them for this card's [When Digivolving] effect?

Answer

No, you can't.

You must delete at least 1 of your opponent's Digimon.

Date
Question

Can I activate this card's [When Attacking] effect, but then choose to not trash any cards in this card's digivolution cards?

Answer

No, you can't.

If this card's [When Attacking] effect activates, you must trash at least 1 card from digivolution cards.

However, if you choose to not activate this effect, it won't activate, and no digivolution cards will be trashed.

Date
Question

If I trash 2 digivolution cards for this card's [When Attacking] effect, do I delete 2 of my opponent's Digimon or Tamers at the same time?

Answer

No, the 2 Digimon or Tamers aren't deleted at the same time.

You repeat this card's [When Attacking] effect of deleting 1 of your opponent's Digimon or Tamers with the lowest play cost for each card trashed from digivolution cards.

In this case, you trashed 2 digivolution cards, therefore you first delete 1 of your opponent's Digimon or Tamers with the lowest play cost, then you again delete 1 of their Digimon or Tamers with the lowest play cost.

Date
Question

My opponent has BT14-062 [Datamon] and a Digimon with a play cost of 7.

If I trash 2 digivolution cards for this card's [When Attacking] effect, can I delete BT14-062 [Datamon] and the Digimon with a play cost of 7?

Answer

No, you can't.

You repeat this card's [When Attacking] effect of deleting 1 of your opponent's Digimon or Tamers with the lowest play cost for each card trashed from digivolution cards.

In this case, you choose BT14-062 [Datamon] as the Digimon with the lowest play cost, but its effect prevents it from being deleted both times.
