Karumonix, the Rat King - Commander (EDH) Pre-Built Decks by Gastooch

Format: Commander

Commander: Karumonix, the Rat King

Bracket: 2

Deck overview

Karumonix, the Rat King is a mono-black rat-tribal beatdown commander. The primary plan is to resolve a critical mass of Rat Colony copies, powering each other up, while Karumonix's toxic 1 turns every connecting Rat into a poison clock. Secondary lines use Piper of the Swarm and Chittering Witch to generate more bodies, Crypt Rats to clear blockers, and Gray Merchant to drain after devotion builds. There is no hidden commander and no infinite combo; the deck wins by combat damage, assisted by poison counters. Recovery is single-card based, and the commander is a strong dig/poison enabler but not strictly required for the 21-copy swarm to function.
