[Opponent's Turn] When an opponent's Digimon attacks, if a card with [Armor Form] in its traits or [X Antibody] is in this Digimon's digivolution cards, you may switch the target of an attack to this Digimon. [All Turns] When this Digimon would be deleted, you may place the top card of this Digimon on top of your security stack face down to prevent that deletion.
