Drivnod, Carnage Dominus

Doubling has always been a black-white pastime of the aristocrats: Teysa Karlov copies death triggers, and various effects double tokens or counters. This one takes the doubling engine and welds it to a Phyrexian body, but the wrinkle is in the wording. It does not double every trigger, and it does not simply copy your death triggers; it fans out any triggered ability of a permanent you control that fires because a creature is dying. That covers your Blood Artist drain, your Zulaport Cutthroat lifeloss, your Grave Pact edicts, your Pitiless Plunderer treasures. Each creature death now resolves the same payoff twice, which turns a slow drip into a flood the moment a sacrifice loop gets going. The 8/3 body reads like a mistake until you notice the second ability accounting for it: exiling three creature cards from your graveyard grants an indestructible counter, and in a deck already feeding creatures to the graveyard for value, that fuel is a byproduct rather than a cost. The Phyrexian mana on both symbols lets you pay the activation with life instead of mana, so the protection stays available even when your black sources are tied up. The design logic is coherent: a fragile threat that survives on the same resource base as the engine it multiplies, built for a deck where creatures dying is the whole plan rather than an accident.
