Imperial Recovery Unit

Crewed white recursion is the trick here. Attacking Vehicles usually want to close games; this one is built to grind, buying back a cheap creature or Vehicle card every time it swings so long as its mana value stays at two or less. That ceiling is the whole balancing act: it turns the engine into a mana-dork retriever, a one-drop hatebear conveyor, an aristocrat-fodder loop, but it will never hand you your bomb back. And because the trigger only fires on attack, the recursion is stapled to combat commitment rather than a passive value tap, so the crew requirement doubles as friction. You tap two power's worth of creatures to animate it, then send a 3/4 into a board where a blocker can trade with a body that was never meant to trade. What makes the piece worth noting is that it launders white's traditionally narrow recursion through an artifact chassis. This is a white card, castable only in white, but the graveyard value that historically ran through Sun Titan and Reveillark now sits on an artifact frame that artifact-matters synergies can care about and that animation effects can target as a nonliving object. The two-or-less clause even lets it return fellow small Vehicles, a quieter note than it looks: it extends white's rebuy toolkit into a card type the color rarely touched.
