Sesshomaru, Unrivaled Demon

Unrivaled Lethality - Double all damage Sesshomaru would deal.

At the beginning of each end step, if Sesshomaru dealt damage to another creature this turn, put a +1/+1 counter on him.

{1}{g}: Regenerate Sesshomaru. (The next time he would be destroyed this turn, instead tap him, remove him from combat, and heal all damage on him.)
