If an opponent's attacking Digimon has the [Deva] trait, does this card's [Opponent's Turn] effect activate?
No. It activates when the security card revealed by a security check is a Digimon card with the [Deva] trait.

If the card revealed for a security check is a Digimon card with the [Deva] trait, can I choose to not activate this card's [Opponent's Turn] effect and not play that Digimon, but still battle with my opponent's attacking Digimon?
No, you can't. This card's effect reads "play it," therefore you must activate it when the card revealed for a security check is a Digimon card with the [Deva] trait.
