<Piercing> (When this Digimon attacks and deletes an opponent's Digimon and survives the battle, it performs any security checks it normally would). [When Digivolving] By returning 1 [Imperialdramon: Dragon Mode] from this Digimon's digivolution cards to the bottom of its owner's deck, none of your opponent's [Security] effects can activate for the turn. [On Deletion] You may play 1 [Wormmon] and 1 [Veemon] from your trash without paying the costs.
