目標生物得-X/-X直到回合結束,X為你墳墓場中牌的數量。
Festive Funeral is still on the stack while you determine the value of X. It doesn't contribute to the value of X.
The value of X is determined only as Festive Funeral begins to resolve. The target creature's power and toughness won't change if other cards are put into your graveyard later in the turn.
