I used this card's [Main] effect to give <Security A. +1> to one of my Digimon with <Armor Purge>, then that Digimon attacked and checked 1 security card. At such times, if that Digimon loses a battle with a Security Digimon and would be deleted, but <Armor Purge> causes a stacked card to be trashed and prevents the deletion, is the additional security check performed?
