Commander: Karumonix, the Rat King

Bracket: 3

Deck overview

Karumonix, the Rat King is the deck's engine and poison vector. Single-faced and with no hidden commander, it runs a rat-tribal swarm plan: fill the board with Rat Colony, Pack Rat copies, and tokens from Lord Skitter, Ogre Slumlord, and Marrow-Gnawer, then use Karumonix's toxic 1 to turn a wide attack into lethal poison, or crack through with Ashcoat pumps. Secondary paths drain life through Ayara, Bastion, Zulaport Cutthroat, and Mirkwood Bats, while Ichor Rats, Infectious Inquiry, Vraska's Fall, and proliferate shorten the poison clock. The mana base is mono-black and straightforward, with rituals and coffers for late-game reach.
