Sacrifice Seal of Removal: Return target creature to its owner's hand.

Sacrificing Seal of Removal is the cost to activate its ability. Once you activate the ability, no player can do anything to Seal of Removal to stop you from activating it. Notably, if you cast Seal of Removal during your turn, you'll have priority to activate its ability before anyone can respond to stop you.
