Kylox's Voltstrider

Vehicles were built to solve a specific problem: how to give an artifact a real body without gifting the opponent a free removal target on the turn it lands. This one takes crew somewhere most Vehicles never go, folding a spellbook engine into the frame. Two separate resource costs shape the whole build. Collect evidence 6 asks you to exile cards with total mana value six or greater from your graveyard to animate the machine, and that same exiled pile is what the attack trigger reaches into, but only for instants and sorceries: any creatures or lands you spent on the evidence sit inert. So the graveyard fuels the animation, and mana fuels the payoff. The exiled spell still costs its full mana price to cast; the vehicle only grants you the permission to cast it from exile mid-combat. Crew 2 keeps the swing cheap. The attack trigger fires during the Declare Attackers step, before blockers commit, so the spell you sling is a proactive play that shapes the combat that follows rather than a reaction to how it resolves: you bet on the swing, not confirm it. The bottom-of-library clause instead of the graveyard is the restraint on the loop. You cannot chain the same exiled spell attack after attack; the engine grinds forward through fresh cards rather than recycling one, which caps how explosive any single swing can get. It is a spells-matter payload wrapped in an artifact chassis.
