Infernal Caretaker

The morph wrapper hides a mass Raise Dead that only cares about one tribe. Pay the face-down , leave a 2/2 on the table, and unflip it for whenever the math favors you: every Zombie card in every graveyard, yours and theirs, returns to its owner's hand. The symmetry is the whole pitch, but in practice it tilts one way. A Zombie deck spends the game stuffing its own graveyard with the creature type, so when the trigger resolves you reload a full grip while an opponent with few or no Zombies in the bin gets almost nothing back. That makes this a tribal payoff first: an engine that converts a board wipe or a long grind into a fresh hand of Zombies to redeploy. The timing matters most after the fact. Flip it in response to a sweeper on the stack, so your Zombies are already in the graveyard when the trigger resolves, and the bounce scoops them back up for a second deployment. Black's relationship with the dead usually runs the other direction (reanimate from the yard, exile to fuel it), so a card that pulls Zombies up to the hand reads as a deliberate inversion: not graveyard hate but graveyard restocking, sized to a creature type built to die and come back more than most.
