Division Table

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.

If you or a permanent you control are instructed to assemble a Contraption, reveal the top card of your Contraption deck. Put it onto the battlefield on one of the three sprockets.

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

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

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.

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

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.
