Jamming Device Rulings
- Jan 19, 2018 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.
- Jan 19, 2018 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.
- Jan 19, 2018 Contraptions are artifacts. Anything that interacts with artifacts will interact with Contraptions.
- Jan 19, 2018 Contraptions aren't put into your main deck. They go into a separate deck called the Contraption deck.
- Jan 19, 2018 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.
