If there is no exiled card as Bishop of Binding’s last ability resolves, most likely because Bishop of Binding left the battlefield while that ability was on the stack, X is 0. The same is true if the exiled card doesn’t have a power, most likely because it’s a noncreature card that had become a creature.
