Q:What does "you may trash any 1 of your opponent's security cards" mean, exactly?

A:This effect allows you to choose 1 card in your opponent's security stack and trash it.

Q:In 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?

A:[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.

Q:If I activate this card's [All Turns] effect when multiples of my Digimon with the [Reptile] or [Dragonkin] trait would leave the battle area at the same time, are all of those Digimon prevented from leaving?

A:Yes, all of those Digimon are prevented from leaving. This card's [All Turns] effect affects all Digimon without having to choose them.

Q:I attempted to delete my opponent's Digimon using this card's 2nd [All Turns] effect when this card would leave the battle area. If another effect prevents my opponent's Digimon from being deleted at such times, does this card leave the battle area?

A:Yes, it leaves.

Q:I attempted to delete my opponent's Digimon using this card's 2nd [All Turns] effect when this card with cards under it would be deleted. If another effect prevents my opponent's Digimon from being deleted at such times, can I use on this card and prevent it from being deleted?

A:Yes, you can. When this card would be deleted, its and 2nd [All Turns] effect trigger simultaneously. Even if you activate its 2nd [All Turns] effect first and the opponent's Digimon can't be deleted, you can then activate the that triggered simultaneously.
