Fume Spitter

Sacrifice Fume Spitter: Put a -1/-1 counter on target creature.

Ultimate Masters

Duel Decks: Mirrodin Pure vs. New Phyrexia

Scars of Mirrodin

Fume Spitter can be the target of its own ability. The ability won’t resolve since it won’t have a legal target, and no counter will be put on any creature, but this does allow you to sacrifice Fume Spitter without another creature to target if you want to.
