Duel for the Throne

Create a red and white 3/3 legendary Human
Shaman Noble creature token and a red and
black 4/2 legendary Human Shaman Noble
creature token. Choose one. Target opponent
gains control of the creature you didn't choose.
As long as you control the creature you chose,
when the creature you didn't choose leaves the battlefield, you gain 5 life, you deal 3 damage to
any target, and target opponent discards a card
at random.
