[Your Turn] All of your Digimon with [Tyrannomon] in their names gain "Piercing". (When this Digimon attacks and deletes an opponent's Digimon and survives the battle, it performs any security checks it normally would.)
[Your Turn] When digivolving one of your Digimon into a Digimon card in your hand with [Tyrannomon] in its name, you may suspend this Tamer to reduce the memory cost of the digivolution by 1.
[Security] Play this card without paying its memory cost.
