Commander: Karumonix, the Rat King

Bracket: 2

Deck overview

This is a Mono-Black Rat tribal deck helmed by Karumonix, the Rat King, built around two interlocking plans: a wide Rat swarm and a poison/infect subtheme. The commander gives every Rat toxic 1, turning the swarm itself into a poison-delivery engine, and digs five deep on entry to stock the hand with Rat bodies. The deck runs a full playset of 15 Rat Colony as its core, supported by anthem effects like Coat of Arms and Ashcoat of the Shadow Swarm, plus a dense proliferate package (Contagion Engine, Contagion Clasp, Karn's Bastion, Blightbelly Rat) to close out poison counters. Secondary wins include Vraska, Betrayal's Sting's ultimate, an infect-boosted Crypt Rats X-damage line, and pure combat damage from an oversized Rat Colony board. It is a grindy, board-building deck that wins through accumulated poison or overwhelming combat, with modest tutor support and almost no stack interaction.
