Bracket: 4

Deck overview

Marrow-Gnawer leads a mono-black rat swarm that plans to out-multiply the table. The deck develops cheap Relentless Rats and Rat Colonies, then uses Marrow-Gnawer's sacrifice ability to turn a small board into dozens of tokens. The main finish is assembling Thornbite Staff on Marrow-Gnawer; because each sacrificed Rat untaps it, the activation can be repeated until the swarm is arbitrarily large. Ayara, First of Locthwain turns those infinite Rat ETBs into a three-player drain. Thrumming Stone provides a secondary way to chain Rats, while Coat of Arms, Bad Moon, and Piper of the Swarm make the horde lethal in combat. The deck is linear, proactive, and combat-focused, with limited stack interaction.
