Battle for Zendikar — Common
Creature — Vampire Assassin Ally
Whenever you gain life, Nirkana Assassin gains deathtouch until end of turn. (Any amount of damage it deals to a creature is enough to destroy it.)
Nirkana assassins craft incurable concoctions by mixing basilisk marrow and deathwillow sap with the vital fluids of a dozen other poisonous species.
