Relentless Dead

Two death triggers, stacked and independent, are the design here. The first offers a single black mana to return the body to your hand for another redeploy; the second offers an X payment to reanimate a different Zombie from your graveyard whose mana value matches what you paid. Because they are separate triggers off the same death, a deck with enough mana can pay both: recur itself for continued pressure and drag a larger Zombie straight back to the battlefield in one shot. The small black cost is what keeps the self-recursion from being free; you have to keep finding mana to keep the loop humming, and the X cost scales the reanimation against how much you can pour in. This sits in black's long line of recursive Zombie engines, where a body that loops cheaply turns sacrifice outlets and death triggers into a repeatable resource. Menace does quiet but real work in that context: a creature that pays out the moment it dies invites a chump block, and forcing two blockers means the body either trades up or connects rather than being eaten for free into a loop you were happy to trigger anyway. The whole package rewards a board built to die on your terms, where each death is fuel to be spent rather than a setback to absorb.
