[On Play] [When Digivolving] If the total cards in both players' security stacks is 6 or less, gain 3 memory, then reveal 1 card from your hand. If you revealed a yellow card, place it on top of your security stack face down. If not, return it to your hand.
[When Attacking] [Once Per Turn] By trashing the top card of your security stack, unsuspend this Digimon, and 1 of your opponent's Digimon gets -7000 DP for the turn.
