Biowaste Blob

A 0/0 body that never lives on its own terms: it enters, pumps itself to a 1/1 through its own anthem, and from there the math compounds. The design is a self-feeding token engine gated behind a single condition, that you control a commander, which turns a format-defining rule into a payoff. Each upkeep spawns a token that's a full copy of the Blob itself, and because every copy carries the same static +1/+1 anthem for Oozes, the buff multiplies rather than sitting flat: two Blobs make each other 2/2, three make each 3/3, and the population feeds the pump while the pump feeds nothing but a bigger population. That is exponential growth wearing the clothes of a green fatty, and the only brake on it is time and interaction, since a single copy left unanswered spirals into a board that outgrows most sweeper math within a few turns. The gating condition costs nothing to satisfy in the environment this engine was built for, since a legend on the field is the default state there rather than a hoop to jump through. The tribe it names has long been thin on payoffs, so a card that both anthems Oozes and manufactures more of them pulls double shifts in a shell that rarely has the density to reward either half in isolation.
