Woodwraith Strangler

Regeneration is normally bought with mana: an open-ended toll you can pay every turn the lands are untapped, with no ceiling on how many times a body shrugs off a kill spell. This Plant Zombie pays in a stranger currency, exiling a creature card from the graveyard per shield, which makes its resilience finite and self-cannibalizing. The wrinkle worth sitting with is that the ability fights its own ideal home: a graveyard-matters deck wants those creature cards parked in the yard for recursion, delve, or reanimation, and every regeneration strips one away. So the cards that could most easily fuel the 2/2 are exactly the cards that least want to spend their fuel this way. The result reads tougher than it plays. It can survive a couple of bad blocks or a destroy effect, but only a handful of times, and only by burning resources other cards put to better use. The reason it never anchored anything is structural: the single ability and the decks that could power it are pulling against each other. What it does cleanly is mark an early experiment with graveyard-as-resource regeneration, from before exile-from-yard hardened into the standard tax on recursion engines rather than a stopgap for keeping a small body alive one more turn.
