Praeter Rykard

Deathtouch, Lifelink
Whenever Rykard, Lord of Blasphemy enters the battlefield or attacks, sacrifice a creature. If you do, create a 4/4 black Serpent creature token with deathtouch and lifelink.

At the beginning of your end step, if you sacrificed a creature this turn, Rykard, Lord of Blasphemy deals damage equal to that creature's power to each opponent.
