(( This is an update to my previous Tezz Servo deck (link in the Based On section below), which I play tested it at FNM, and lost to every single green aggro, except one. Considering this, I want to bring more options to the table to defend while setting up. This time, I have removed the entire Tezz portion, relying solely on servos and improvise. ))
The goal with this deck is to blanket place improvise on all non-artifacts using Statuary, bring them in quick to produce servos, and utilize those servos as colorless mana via improvise. You can combo using cards such as Panharmonicon, for example, to have any servo-producing cards produce an additional servo per Pan. Pan also works on Fabricate, which gives you the option of, for example, either creating 3x2 servos OR placing 3x2 +1/+1 counters on Marionette Master. Mechanized Production on artifacts such as Panharmonicon or the Servo-producing artifacts can prove lethal after a couple turns. Also note that Mechanized Production guarantees a win once 8 of any same-name artifact are in play, including servos.
Battle at the bridge has proven to be an incredibly effective card. It only costs 1 black (X/1U), and you can tap ANY and ALL artifacts to not only bring down opponent creatures, but to restore life equal to the number of artifacts you tapped. When used properly, this card can give you a significant life buffer while setting things up.
While Cogworker's Puzzleknot is in primarily for producing servos (and can be a target for Mech Production), it also has the option of sacrificing it, which combos with Marionette Master's second ability, which deals life loss equal to her power. This is also why I have Implement of Examination, which allows you to sacrifice it for 1 Blue, you draw 2 cards, and if Marionette is in play, again, life loss. Between Cogworker's Puzzleknot, Implement of Examination, Marionette, and Mechnized Production, you have the option to ping your opponent for a good deal of life loss is played properly.
