Insufferable Syphon

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

While Contraptions you control are on the battlefield, the Contraption deck is not, even if you are using it to signify the three sprockets.

In silver-bordered games using Contraptions, you have three sprockets, illustrated on the back of Contraption cards. At the start of the game, put a CRANK! counter on sprocket 3.
