[When Attacking] You may play 1 Digimon card with [Sistermon] in its name from your hand or trash without paying its memory cost. [Your Turn][Once Per Turn] When you play another Digimon, this Digimon gets +3000 DP and ＜Piercing＞ for the turn. (When this Digimon attacks and deletes an opponent s Digimon and survives the battle, it performs any security checks it normally would.)
