Survivor of the Unseen

Draw two and put one back on top is among the most efficient card-advantage motors blue has ever priced this cheaply: net positive flow plus selection, repeatable every turn. But the engine is bolted to a self-immolating chassis. The compounding upkeep tax means the first upkeep after it lands costs to keep the body alive, the next , the one after , and the curve climbs until the math collapses and you sacrifice it. That converts a permanent advantage engine into a fuse: you know going in roughly how many activations you can wring out before the upkeep cost outruns your mana, and the design dares you to extract every draw before it burns down. The filtering half leans into a quieter trick, since you control what sits a tick from your next draw step: stash a removal spell or a threat one card deep, and the tap becomes a setup tool rather than pure refill. The honest counterplay against the clock is to reset it (a flicker effect wipes the age counters clean), though the freshly returned copy enters with summoning sickness and sits idle for a turn, so even the escape hatch costs you tempo. It is a fragile, time-limited Wizard whose worth is meant to be spent before the counters bury it, a sharper bit of self-limiting design than the 2/1 body suggests.
