Timeless Witness

Regrowth stapled to a body has been printed before, but the eternalize clause is what makes this version keep giving. The 2/1 front half is deliberately fragile: it trades in combat, dies to any burn, and once it hits the yard it can turn around and buy a second graveyard grab as a 4/4 Zombie token. That two-stage structure is the whole design logic. The front side is a cheap, disposable value engine that wants to die; exiling it to eternalize converts that spent card into an expensive, resilient one whose enter trigger pulls another card back from the graveyard. Green's history with graveyard return has always leaned toward one-shots (Regrowth, Nature's Spiral) or narrow recursion tied to creatures; the move here is bolting the return trigger to a creature that can then eternalize into a second, tougher version of the same effect. That the original body cannot recur itself (eternalize exiles it as a cost, so it is gone for good) is the honest limit on the loop: you get the trigger twice, not forever. Eternalize also sidesteps the fragility on both axes: the token arrives as a black Zombie, uncoupled from its green source, and its 4/4 body is far harder to answer than the original. It reads as a modest value creature and functions as a two-for-one that stays dead only after it has paid out twice, the sort of grinding attrition green rarely gets to play with.
