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 If you have another Digimon in play, 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.)
