Dimetromon

Q:If I activate this card's [All Turns] effect when multiples of my other Digimon with the [Reptile] or [Dragonkin] trait would leave the battle area at the same time by my opponent's effects, 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: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.
