Gutter Grime
An enchantment that turns death into accumulation. The single slime counter it gains each time a nontoken creature you control dies does double duty: it grows the running total and sizes every Ooze the engine has ever spat out, since each token reads its power and toughness off the same shared counter. That second clause is the design's quiet leverage. You are not making a 1/1 then a 2/2 then a 3/3; you are building a board where the fourth creature to die hands you a fresh 4/4 and simultaneously inflates the three Oozes already standing into 4/4s alongside it. The counter is a single dial that scales the entire token swarm at once. The deliberate hole is the nontoken restriction: the Oozes it produces cannot feed it, so the engine refuses to eat its own output and demands a steady supply of real creatures from elsewhere. That pushes the card toward sacrifice fodder and aristocrat shells rather than self-contained loops, the friction that stops a five-mana, blank-on-an-empty-board enchantment from spinning into free value. Left alone with a sacrifice outlet and a stream of expendable bodies, it converts a graveyard's worth of small creatures into a board of identical, ever-larger tokens, all keyed to one number.
