Goblin Intellect

Reveal the top seven cards of your library. You
may exile any number Mountain cards revealed this way and put all other cards on the bottom of your library in any order. Assemble a Contraption for each Mountain card exiled this way.(To assemble a Contraption, put the top card of your Contraption deck face up onto one of your sprockets.)
Harnessing the power of absurdity is what goblins do best.
