Dark Revenant

Most recursion in black runs through the graveyard, and this Spirit looks like it sidesteps that exposure by going to the top of your library instead. It does not. The death trigger has to use the stack like any other, which means the creature still passes through the graveyard on its way home, leaving a window for instant-speed graveyard hate to exile it before the trigger resolves; a replacement effect like Rest in Peace stops it from dying at all and takes the return with it. What the design actually buys is not immunity but a different shape of value: persistence rather than card advantage. The same 2/2 flyer comes back over and over, but it never nets you a card, because the return costs you next turn's draw step. You do not draw something new; you draw the body you already paid four for. That self-imposed draw tax is the price that keeps the recursion fair, and it is paid every single time. The flying is what makes the loop worth running: it lets the Spirit die productively in the air, trading up or chumping an evasive threat, then climbing back onto your library to do it again, rather than rotting as a permanent blocker. It sits in a small line of black creatures that try to recur without leaning on the graveyard's contents, swapping raw power for a resilience that is real against most disruption but, crucially, not against all of it.
