Gobbling Ooze

The problem with sacrifice-fueled growth is that it costs a card every time, and a 3/3 for five asking you to feed it your other creatures one at a time is a slow trade in any deck that cares about board presence. The ability is repeatable but linear: a green mana plus a body buys exactly one counter, with no death-trigger payoff, no token generation, and no way to convert the sacrificed creatures into anything except size on a single attacker. That puts it at odds with how green usually wants to spend its dorks, since the color's best aristocrats-style payoffs live in black, and the Ooze offers nothing to a board you would rather keep wide. Where the design points is toward a deck built to manufacture chaff: token makers, recursive fodder, creatures that want to die anyway. Feed it disposable bodies and it climbs past the range of most combat math, but it remains a mana-and-card sink that does its work over multiple turns rather than in one explosive activation. As an outlet it is honest and unglamorous; it eats creatures and grows, and the absence of any secondary upside is exactly what keeps it from being more than a curiosity in formats where sacrifice fodder is a renewable resource.
