Cloakwood Hermit
The Background type exists to bolt a second identity onto a commander, and this one grants a graveyard-driven token engine to every commander creature you own rather than to a single leader. The wrinkle is the condition: it does not care what you sacrifice or how the creature dies, only that a creature card hit your graveyard from anywhere this turn, which folds fetch-and-mill effects, edicts, combat losses, and your own aristocrat outlets into the same trigger. Two tapped Squirrels per end step is a modest clip, but the tokens arrive tapped precisely because they are meant to accrue across turns as fodder, not to swing the turn they appear. That gating (one check per end step, off a single creature death anywhere) is what keeps a board-wide grant from spiraling; the ceiling is a function of how many commander creatures you have partnered into play, not of how many creatures you can kill in a turn. It reads as a small enchantment, but structurally it is a payoff piece looking for a graveyard-heavy shell, one that turns the incidental creature deaths a sacrifice deck already generates into a slow, recurring army. The Squirrel choice is a nod to green's long-running token tribe, tying the design back to a flavor thread green has carried since well before Backgrounds existed.
