Undergrowth Scavenger

A 0/0 that prints its own body straight from the graveyards, reading every discard pile in play rather than only its controller's. Because the counter count locks in the moment it enters, the entire card lives or dies on one question: how many creature cards sit across all yards right now? Cast it into empty graveyards and there is nothing to read, no counters to place, and the body fails the 0/0 state-based check the instant it resolves: four mana for a creature that hits the bin before it ever sees combat. That timing is the whole constraint. It belongs to the lineage of graveyard-as-resource creatures that scale off the pile rather than recur out of it, scoring the yard once for a flat bonus instead of looping anything. The shared pool is its best feature: counting opponents' fallen creatures alongside your own self-mill means a grindy attrition game or a fresh board wipe can suddenly make it land as a real threat. It is a back-half payoff, not a curve-filler, and it wants strategies that fill graveyards passively while leaving them intact: self-mill, fight-heavy boards, sacrifice loops. The one thing it does not want is anything that exiles creatures from the yard before it enters, since every card removed is a counter it never gets. Once those counters are placed they stay, so the card is a single front-loaded payment, never an engine.
