Biogenic Ooze

The classic exponential engine dressed in green. A single 2/2 body arrives with a friend, and from there the math takes over: every end step swells the whole board while the activated ability keeps adding fresh 2/2s that immediately catch the counter train. What makes the design work is that it stacks two clocks against each other. The counter trigger scales the width you already have, and the token ability buys more width to scale, so leaving this alive one extra turn does not add one creature; it adds a creature and grows everything else. That compounding is why the card reads as fair on the turn it lands and lethal two turns later, and why the sorcery-speed reality of it (the counters only accrue on your own end step) matters: an opponent who answers it at the right window pays far less than one who waits. It is the green counters-matter payoff distilled to a mana sink that never stops being relevant, the antithesis of a topdecked do-nothing in the late game. The five-mana body is deliberately unimposing on its own; the whole threat lives in the second and third turn of the accrual, which means the card punishes decks built to trade one-for-one and rewards the flood of mana green tends to generate anyway.
