Sacrifice a creature: Put a charge counter on this artifact. , Remove two charge counters from this artifact: Create a 2/2 colorless Spawn artifact creature token.

: Add two mana of any one color. Spend this mana only to cast artifact spells or activate abilities of artifacts.

, Sacrifice this artifact: Put a +1/+1 counter on target nonartifact creature. That creature becomes an artifact in addition to its other types.

Whenever this creature or another artifact creature dies, you may untap target artifact.
