Refibrillator

Any Contraption that's on the battlefield and wasn't assembled immediately heads to the scrapyard. However, if it's a not an actual Contraption card (like Copy Artifact isn't), it goes to your graveyard as normal. Non-Contraption cards can't be in the scrapyard.

If you or a permanent you control assembles a Contraption and your Contraption deck is empty, nothing happens. You don't lose the game.

In Constructed formats, a Contraption deck must have at least fifteen different Contraption cards and no more than one of each.
