Assemble

Assemble is a keyword action introduced as a joke in Future Sight and related to Contraptions. It was greatly expanded upon in Unstable, where it was one of the main silver-bordered mechanics. Contraptions may be assembled by players and/or Creatures (Riggers). 
==Description==
To assemble a Contraption means putting the top card of your Contraption deck face up onto one of your three sprockets. 
There is no functional difference between players assembling a contraption, and creatures assembling a contraption. However, <c>Steamflogger Boss</c> only cares about Contraptions assembled by creatures.
===Reassemble===
Reassemble is a related keyword, featured on <c>Suspicious Nanny</c> and <c>Cogmentor</c>. It means (to gain control) and move it onto (another) one of your sprockets. You don't have to advance it in the normal direction.
==History==
It was stated that this mechanic and Contraptions were meant as a joke. Forsythe's statement ensured that players wanted it and they've bugged Mark Rosewater about it ever since. Thus, Rosewater vowed to figure out contraptions' design before he would retire.
==Rules==
==Rulings==
* If a card instructs you or a creature you control to assemble a Contraption, but your Contraption deck is empty, then nothing happens.
