Bulette

A green vanilla 3/3 at four mana would be embarrassing on its own; the death-trigger is what turns that plain body into a payoff for a strategy green rarely gets to run. The condition is broad in the way that matters most: any creature dying anywhere on the turn feeds the counter, so it does not care whose creature it was, only that something hit a graveyard. Combat trades, sacrifice fodder, and even an opponent's chump blocks all pump it, and the growth is permanent rather than a temporary swing. But the trigger keys specifically on death, so an opponent who bounces or exiles their blockers instead of trading denies the counter entirely; the removal that fills a graveyard is what feeds it, and the removal that empties the battlefield another way does not. The end-step timing is the quiet governor: you cannot chain the counter within a single turn, and the trigger fires once no matter how many creatures fell, so the Bulette grows steadily rather than exploding. That pacing keeps a snowballing beater fair. It rewards a board where creatures are already dying on their own schedule, which is a decidedly un-green thing to build around; the card sits at the seam between attrition and aggression, a beast that gets bigger the more the battlefield churns. The flavor tracks the mechanic exactly: the landshark surfaces to devour whatever falls, and each meal leaves it larger.
