Artifact Creature — Robot Soldier

Whenever you cast an Aura or Equipment spell, put a +1/+1 counter on this creature. When this creature dies, create X Junk tokens, where X is the number of +1/+1 counters on it. (They're artifacts with "{T}, Sacrifice this token: Exile the top card of your library. You may play that card this turn. Activate only as a sorcery.")
