Q:I used this card's [On Play] [When Digivolving] [When Attacking] effect to delete an opponent's Digimon with an [On Deletion] effect, and I used the part of the effect after "then" to return that card from their trash to the bottom of the deck. Can that deleted card's [On Deletion] effect activate at such times?

A:No, it can't be activated. When a card with an effect that's pending activation leaves its current area while activation is pending, the effect can no longer be activated. In this case, the deleted card's [On Deletion] effect triggers, but it's removed from the trash before the effect can activate.

Q:What happens to cards placed face up in the security stack by effects?

A:They become face-up security cards that remain revealed. Other than rules that specify face-up security cards, the rules apply in the same manner as standard security cards.

Q:What happens upon a security check for a security card that is placed face-up?

A:The check is performed with the card left revealed. Other than rules for cards left revealed, the rules apply in the same manner as standard security checks.

Q:Does a card's [Security] effect trigger upon a security check with that card placed face-up?

A:Yes, it triggers.

Q:What happens if I shuffle a security stack that includes security cards placed face-up?

A:Any face-up cards are placed face down, then you shuffle the cards. After shuffling, all cards are left face-down.
