Soulless One
Most lord-style payoffs count only what you control; this one reads the entire game's Zombie census. Its stats track every Zombie in play, regardless of whose, plus every Zombie card sitting in any graveyard, which tethers its size to the accumulated debris of the whole match rather than to a single board state. That choice inverts the usual incentives. A tribe defined by recursion and self-sacrifice (Zombies have always fed the graveyard willingly) turns its own dead bodies into power and toughness, and the longer the game grinds, the larger this thing swells, growing off creatures it never owned in the first place. The floor is the same clause running at its lowest setting: because it is itself a Zombie, it always counts at least one (itself) in play, so it arrives as a 1/1 with every other yard and board empty. That minimum is what keeps the engine honest. Cast alone at four mana, it is barely a body. Inside a shell that mills, sacrifices, and rebuys its dead, the clause stops being bookkeeping and becomes a clock that compounds with every Zombie that hits a graveyard. It is a payoff that scales not with your investment this turn but with the total mortality the game has produced, an unusual axis for a creature whose entire value sits in a single counting clause.
