Transmute Artifact

Sorcery, UU (2)
As an additional cost to play Transmute Artifact, sacrifice an artifact.
Search your library for an artifact card. If that card's converted mana cost is less than or equal to the sacrificed artifact's converted mana cost, put it into play. If it's greater, you may pay the cost difference. If you do, put it into play. If you don't, put it into its owner's graveyard. Then shuffle your library.¹
