Luxurious Locomotive

A Vehicle that pays you for the act of attacking rather than for connecting. Crew is usually a downside: you tap creatures away from combat to animate a metal body, trading board presence for a single evasive threat. Here the tapping is the payoff. Each creature that crewed this turn yields a Treasure the moment the Vehicle swings, so the tension between "attack wide" and "assemble a fast mana pile" collapses into one attack step. The Treasure trigger keys off crew, not damage, which means the ramp lands even into a wall of blockers or a wrath waiting on the stack; you get paid for declaring the attack, full stop. Crew 1 keeps the price of admission trivial, so a single mana dork or token can turn on a 6/5 and mint at minimum one Treasure, and the ceiling scales with however many bodies you can afford to sit out of the fight. The "activate only once each turn" clause is the balancing wire: no rebuilding a crew mid-combat, no stacking multiple crew activations to farm extra tokens off one swing. What results is an aggressive-ramp piece that rewards a wide, expendable board rather than a lone big creature, and reframes the crew keyword from a tax into an engine.
