The self-milling reanimator has always had to solve one problem: filling the graveyard is easy, but getting the payoff to line up with the fuel is where the archetype's engines wobble. This one folds both halves into a single body. The entry mill loads the yard; the death trigger cashes it back out, exiling itself to return a creature you dumped there on the way in. That symmetry is why the small, cheap frame works: a 2/1 flier trades or chumps freely, and every time it dies it converts a milled creature into a card in hand, so the recursion is priced into the body rather than bolted onto a separate spell. The exile-on-death clause is the discipline here. Because returning the target requires the card to remove itself, there is no infinite recursion loop and no permanent value engine; you get one conversion per copy, then it is gone. That keeps the effect honest for an ability that would otherwise stack too cleanly with blink and sacrifice loops. The flying is not decoration either: it makes the 2/1 an evasive attacker that dies on its own terms rather than sitting back, and a flier that wants to trade suits a reanimation shell perfectly, because such a shell is happy to throw the same body away twice.
