Talking Donkey

Warning Voice — When Talking Donkey enters the battlefield, you may reveal a card named Angel with a Drawn Sword from your hand. If you do, tap target creature an opponent controls. It doesn't untap during its controller’s next untap step.

Whenever Talking Donkey becomes tapped, you may surveil 1. (Look at the top card of your library. You may put it in your graveyard.)
