Salvation Engine

Crew 6 is a steep gate, and the joke of the design is that the Vehicle itself lowers it. Every other artifact creature you control gets +2/+2, so the same board that turns the key is the board this thing just inflated: a pair of two-power robots become four-power robots, and the six you owe is trivial to muster from bodies you already committed. That circularity is the payoff structure. Once it swings, the attack trigger turns combat into a rebuild line, each hit returning any artifact card from your graveyard: a mana rock to reset, a Vehicle to widen, a fresh artifact creature to feed the anthem next turn. The target is a resource decision as much as a combat one. A 6/10 that wants to be an engine rather than a beater is an odd shape for a body this large, but the toughness is the point; it survives the ground stalls where artifact-creature decks tend to clog, and the recursion means those stalls are precisely when it starts pulling ahead. The cost is honest: it does nothing the turn it lands, and a swept board leaves an anthem buffing no one and a Vehicle no one can crew. Build the artifact density it demands and every attack compounds; skimp on it and you own an expensive statue.
