Dr. Doofenshmirtz

Suspend 2 — {1}{u}, Sacrifice an artifact
When Dr. Doofenshmirtz enters the battlefield,
reveal cards from the top of your library until
you reveal an artifact card. Put that card onto
the battlefield and the rest into your graveyard.
Then, if you have no cards left in your library
you lose the game.
