Avacyn Restored — Common
Target creature gains deathtouch until end of turn. Regenerate it. (The next time that creature would be destroyed this turn, it isn't. Instead tap it, remove all damage from it, and remove it from combat. Any amount of damage a creature with deathtouch deals to a creature is enough to destroy it.)
An undead snake doesn't bite in self-defense. It hungers as any zombie, never sated.
