Bee-Bee Gun

If a Contraption would leave the battlefield and go to any zone other than exile, it instead goes to the scrapyard, the Contraption deck's version of the graveyard. Things that affect the graveyard do not affect the scrapyard. You can exile Contraptions just fine.

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

While Contraptions you control are on the battlefield, the Contraption deck is not, even if you are using it to signify the three sprockets.

Contraptions are artifacts. Anything that interacts with artifacts will interact with Contraptions.

Contraptions aren't put into your main deck. They go into a separate deck called the Contraption deck.

In Limited formats, a Contraption deck may include any number of Contraption cards in your card pool. You don't have to include every Contraption card you draft or open in sealed deck. In those formats, your Contraption deck may include duplicates.

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 silver-bordered games using Contraptions, you have three sprockets, illustrated on the back of Contraption cards. At the start of the game, put a CRANK! counter on sprocket 3.
