Aatchik, Emerald Radian

Two payoff engines stacked on one body, aimed at two different kinds of deck. The enters trigger reads a graveyard the way a self-mill or aristocrats shell fills it, converting every artifact and creature card in the yard into a swarm of 1/1 Insects, so the burst scales with a strategy that treats the graveyard as a resource pool rather than a loss. The second ability then turns that swarm into an attrition clock: each Insect that dies grows the body by a +1/+1 counter and costs every opponent one life, the classic aristocrats sacrifice loop reframed through a creature type. The elegance is that the two halves feed each other. The first makes Insects; the second rewards their deaths; a sacrifice outlet closes the circuit and converts a pile of tokens into life-loss and a mounting threat. What keeps the design in check is the sequencing tax: the token count is fixed on entry, so the initial swarm is only as large as the graveyard you built beforehand, and the counter-and-life-loss half needs those tokens to actually die, meaning the payoff is deferred behind an outlet you have to supply yourself. It is a commander-scale synthesis of two black-green traditions, graveyard value and aristocrat life-loss, routed through a tribe that Golgari has rarely built around at the helm.
