Rapid Prototyper

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.

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