Sproutback Trudge

Lifegain usually buys you a buffer; here it buys you a discount and a second life for the same fatty. The printed cost is a nine-drop, but the reduction scales with how much life you gained this turn, so in a deck built to spike a big gain on a single turn the sticker becomes almost decorative: a single lifelink swing shaves a few, an Aetherflux Reservoir turn or a dedicated soul-drain engine can shave most of it, and the trample body lands well ahead of schedule. The recursion clause is the part that changes how you sequence a turn: because it checks at your end step and casts the creature straight from the graveyard, chump-blocking or trading it away is not the punishment it looks like, provided you keep the life ticking each turn. That turns green's incidental lifegain (normally a soft, defensive resource that does nothing to close games) into a repeatable cost-reducer and an on-demand recursion engine for a hard-to-kill threat. Green's fatties have historically leaned on mana efficiency and raw size; this one instead taxes your ability to generate a spare resource elsewhere, then rewards the payoff deck with a beater that keeps coming back. The design lives entirely in that conversion: the more of your turn is spent gaining life, the cheaper and stickier the trampler becomes.
