Toxic Ascendancy

Toxic Ascendancy is a 4-color (WUBG) Infect/Poison proliferate Commander deck, likely built around Atraxa, Praetors’ Voice and other toxic/infect threats like Ixhel and Vishgraz.

Its game plan is to land an early infect or toxic creature—such as Glistener Elf, Blighted Agent, Plague Stinger, Bilious Skulldweller, or Venerated Rotpriest—and quickly give opponents poison counters. From there, it snowballs by using proliferate engines like Atraxa, Evolution Sage, Inexorable Tide, Tekuthal, Flux Channeler, Thrummingbird, Contagion Clasp/Engine, and Karn’s Bastion to multiply poison counters without needing to keep connecting in combat.

The deck plays like a fast, resilient poison-based midrange/combo-control shell, with strong ramp, tutors, and protection/countermagic to force through its threats and defend them. It typically wins by getting each opponent to 10 poison counters, sometimes via evasive infect creatures, Inkmoth Nexus,
