Northern Princess in the Deep Sea

【AUTO】 When a card named "Sink!" is placed on your climax area, if this card is in your center stage, choose up to one of your opponent's level 0 or lower characters, put it into his or her waiting room, and reveal the top card of your deck. If that card is a level 0 or lower character, put it into your hand. (If it is not, return the revealed card to its original place)
