Transmute Artifact
Sorcery
Sacrifice an artifact. If you do, search your library for an artifact card. If that card's mana value is less than or equal to the sacrificed artifact's mana value, put it onto the battlefield. If it's greater, you may pay X generic mana , where X is the difference. If you do, put it onto the battlefield. If you don't, put it into its owner's graveyard. Then shuffle.

The sacrifice of an artifact is an effect of the spell, not a cost, which means it happens as the spell resolves. If Transmute Artifact is countered, you do not have to sacrifice an artifact.

Additional mana spent to cover the differences in mana costs is not part of the mana cost of this spell. It is spent during spell resolution.

The one from the library enters when the spell is resolved, and this does not count as the casting of an artifact.
