UnCommander Rulings
Contraption cards aren’t put into your deck, they are put into a separate contraption deck that is played with your main deck.
Contraption decks in constructed play, like the UnCommander formats, must consist of 15 or more contraption cards, all with different names. Color identity rules also apply to a cards in contraption deck. Therefore, none of them may have colors in their color identity not also in the color identity of the commander of the main deck the contraption deck is played with.
For the rules on how contraptions and the contraption deck functions, see the gatherer rulings below and the Unstable FAQ article
