The Beast, Deathless Prince - 2BR
Legendary Creature — Demon (Rare)
When you cast this spell, gain control of target creature until end of turn. Untap it. It gains
menace and haste until end of turn.
The Beast enters the battlefield tapped with six stun counters on it.
Whenever a creature deals combat damage to
its owner, untap The Beast and draw a card.
6/6
Woah that's a cool take on Act of Treason! You want to actually hit with what you steal instead of just sac it or whatever. (Granted you probably still sac it, but at least you have the one extra hoop).
