Sorcery, 2U (3)
Uncommon
As an additional cost to cast Tinker, sacrifice an artifact.
Search your library for an artifact card and put that card onto the battlefield. Then shuffle your library.
"I wonder how it feels to be bored."
—Jhoira, artificer
Illus. Mike Raabe

10/4/2004: Because the "search" requires you to find a card with certain characteristics, you don't have to find the card if you don't want to.
