Arcum complete

Affinity for artifacts (This spell costs less to cast for each artifact you control.) Artifact creature spells you cast have affinity for artifacts. (They cost less to cast for each artifact you control.)

: Target artifact creature's controller sacrifices it. That player may search their library for a noncreature artifact card, put it onto the battlefield, then shuffle.

Creatures don't untap during their controllers' untap steps. Whenever a creature enters, untap all creatures.

When this creature dies, return another target artifact card from your graveyard to your hand.
