Nettletooth Djinn

Green was not supposed to get a body this size for this little, and the upkeep self-damage is the tax it paid for the privilege. This is the old design grammar of the drawback creature: a stat line above the curve handed to a color that was not meant to have it, balanced not by a cost an opponent pays but by a recurring bleed the controller absorbs. One damage per upkeep is small math, but it compounds, and against an aggressive opponent the clock you set on yourself can close a game your beater was supposed to win. The discipline is that the damage is unconditional and untargetable: no sacrifice clause, no way to switch it off, no battlefield state that suppresses it. You commit to the bleed the moment the creature resolves, and you keep paying for as long as it lives. It belongs to a whole generation of green fatties priced this way, the lineage that runs through Force of Nature and its kin, where green got to be big only if it agreed to hurt itself for the size. Later design largely abandoned the self-damage drawback in favor of cleaner downsides, conditional bodies, or simply charging full rate, which is why this reads now as an artifact of a specific moment in how green's bulk was rationed.
