Sorin, Innocent of Innistrad

Lifelink (Damage dealt by this creature also causes you to gain that much life.)
Whenever you gain 10 or more life on one single turn, exile Sorin, Innocent of Innistrad, then return him to the battlefield transformed under his owner's control.
"You are my grandson and I want you to be a part of this ritual."
- Edgar Markov to Sorin
