Mortivore

The Lhurgoyf design begins from a single premise: a creature whose size is the graveyard made flesh, counting every dead creature across all yards into power and toughness. What separates this one from its green progenitor is not the count but the color it lives in and the protection that comes with it. A graveyard-scaled body is usually a paper tiger; the moment it grows large enough to matter, removal sends it to the graveyard where it can no longer threaten anyone. The regeneration shield is what makes the size stick. Pay one black mana and the kill spell becomes a tap, the combat block becomes wasted, and the body heals back to its full count. The feedback loop is what gives the card its menace in a long game: attrition feeds both graveyards, so the size climbs without the controller doing anything but surviving, and a sweeper that clears the board leaves a regenerating finisher standing on a freshly stocked count. Removal that does kill creatures simply adds to the resource pool it reads from. The tension this resolves is the classic graveyard-payoff problem, the choice between a finisher that is huge but fragile or small but durable, by funding the protection from black mana while the shared pile of bodies fuels the size.
