What happens if this card is flipped over upon a security check from an opponent's Digimon's attack in a state where a "your opponent's <Security> effects don't activate" effect has activated?
Since the <Security> effect didn't activate, the battle proceeds normally. At the end of the battle, this card is trashed.
