Seed Guardian

A green body that punishes its own removal: kill it cheaply and the controller hands back a token sized to whatever has been stacking up in the graveyard. The design folds two long-running green themes into one card. There is the death-as-engine idea, the lineage of creatures that demand an answer twice (the way a Wurmcoil Engine or a Carrion Feeder build a board out of dying things), and there is the graveyard-as-resource idea that green and black have shared since the earliest recursion cards. What makes the replacement token interesting is that its size is not fixed at any printed number; it scales with how deep the deck has dug, so a self-mill or sacrifice shell turns a 3/4 into a death-trigger that leaves behind something far larger. The reach is the quiet glue: it makes the front half a real defensive blocker, which matters because the card wants to trade or be removed rather than survive, and a creature that gladly blocks fliers gets into combat sooner. The result is a midrange body that resists the cheap removal spells it would otherwise fold to, while rewarding a deck already invested in filling its own graveyard.
