This ruthless loop turns a simple sacrifice outlet into a total battlefield lock by combining continuous stat grants with cascading death triggers. Carrion Feeder acts as the engine, letting you sacrifice creatures to build its own power while sparking a devastating chain reaction. Because Archetype of Finality grants deathtouch to your entire team—while stripping it from your foes—every single creature you control natively satisfies the death condition for The Serpent Society. Whenever a sacrifice forces an opponent's nontoken creature to bite the dust, Overseer of the Damned steps in to harvest the tragedy, spawning a tapped 2/2 Zombie token that instantly gains deathtouch from the Archetype. This creates a self-sustaining cycle where those newly minted Zombies can be sacrificed right back to the Feeder, wiping away every nontoken creature your opponents control and locking them out of the game for good.
