Jamming Device (UST-192) is an Unstable artifact Contraption that belongs to the Contraption deck and uses the game's CRANK mechanic. Whenever you crank this Contraption, it gives creatures a target player controls -1/-1 until end of turn, providing small, repeatable creature suppression. As a Contraption it is assembled from and managed by the separate Contraption deck and interacts with sprockets and the scrapyard rather than the regular graveyard.
