A player affected by this card can sacrifice a permanent any time he or she could cast an instant. This is a special action that doesn't use the stack and can't be responded to.
8/1/2008
A player can only sacrifice a permanent to end this effect if he or she has more permanents than any other player, and he or she hasn't already sacrificed a permanent to end the effect this turn. The ability to sacrifice a creature is granted by the same effect that is being ended.
