All permanents are artifacts in addition to their other types. All cards that aren't on the battlefield, spells, and permanents are colorless. Players may spend mana as though it were mana of any color.

Tap two untapped artifacts you control: Untap target artifact.

Sacrifice a creature: Target player mills cards equal to the sacrificed creature's power.

Whenever this creature becomes tapped, you may create a 1/1 blue Merfolk Wizard creature token.
