Shortcut to Mushrooms
Green almost never gets a reason to want its own permanents in the graveyard: the color's counter payoffs overwhelmingly ask you to keep bodies on the table and grow them. This inverts that instinct. The end-step check rewards a sacrifice-adjacent build where fetchlands crack, tokens expire, and creatures get fed to an outlet, converting what green usually experiences as attrition into a repeatable growth trigger. The reward is deliberately flat rather than scaling: one permanent leaving nets exactly one +1/+1 counter, the same yield whether a single thing died or five did, which is what keeps this a build-around rather than a snowballing engine. The sharper constraint is timing. Because the counter arrives only at the beginning of your end step, a departure has to occur on your own turn to register; permanents that leave during an opponent's turn (chump blocks, removal traded away, an instant-speed sacrifice on their end step) contribute nothing. So the deckbuilding question becomes proactive volume across your own turns, not reactive trading across the whole cycle. The Ring temptation on entry folds a permanent-based enabler into the broader Ring-bearer subtheme, giving a static engine a reason to sit beside creatures that care about the emblem. The result is a modest effect wrapped around a condition that is trivial to satisfy in a deck built for departures and inert in one that isn't.
