Inflation Station

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.

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

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

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.

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.

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.

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

At the beginning of your upkeep, if you control any Contraptions, move the CRANK! counter to the next sprocket. You may then crank any number of Contraptions on that sprocket, causing their abilities to trigger. Cranking a Contraption is always optional.
