$20 standard constructed tourney deck (Standard)

Idea is to replace servos as you use them, maybe even get two for one, if everything lines up. If you get more than one Hidden Stockpile out, it escalates. This deck requires 5 turns if the cards come out just right to work perfectly, with low level creatures and minor control to hold back opponent while scry/draw helps find parts; with a $20 limit and standard only, I'm hoping fast, face-smackin' decks will be harder to build without the all-star team.

Defiant Salvager gets +1/1 counters as long as you have an artifact or creature to sacrifice and with Animation Module plus 1 colorless mana, then you get a servo. Servo is an artifact creature, so one is needed to start things going; Servo schematic works as well, and it gives another servo when dying. With Inspiring Statuary, tap the artifact before you sacrifice it to pay mana cost. Sacrificing triggers 9th Bridge Patrol to get a +1/1 counter, spend another colorless mana, get another servo from Animation Module. If you have Hidden Stockpile out, each time you sacrifice an artifact, you get an additional servo to tap and sacrifice, and the scrying is cheap. Merciless Resolve gives a BW deck decent draw. Campaign of Vengeance is the kicker: build a swarm of servos, attack with your infinitely pumped defiant salvager and 9th Bridge Patrol and 25 servos. That's -27 life to opponent and +27 to you. Before any any battle damage.

Gifted Aetherborn, if it pops up is a cheap cast to hold off attacks while building up pieces. Aetherborn Maurader can scoop up +1/1 counters (another servo) to use flying and lifelink. Sram's Expertise for a free cast and 3 servos for 2nd way to get things going, Visions of Brutality to neuter threats.

Inspired by deck named Orz ServoSwarmNuke by khanthemighty. Central idea tweaked with cheaper cards and better combo, I think. This is for a standard constructed deck tournament at my local LGS. Value of your 60 card registered deck is limited to $20, per tcg website.

If not limited to Standard, Ajani's Pridemate makes this combo crazy with Campaign of Vengeance, and/or to a lesser degree lifelink from Gifted Aetherborn/Aetherborn Maurader.
