Deck overview

Rat Colony swarm deck built to use Marrow-Gnawer as a multiplicative token engine. The primary plan is to establish an early rat presence, then either chain Rat Colonies through Thrumming Stone or repeatedly activate Marrow-Gnawer with Thornbite Staff to create an arbitrarily large army. Secondary paths use Lord Skitter/Sewer King, Pack Rat, and Piper of the Swarm to generate incremental rats, with pumping and evasion from Bad Moon, Icon of Ancestry, and Rogue's Passage. Karumonix and tutors provide consistency, while Patriarch's Bidding and Oversold Cemetery recover from sweepers. The deck wins through overwhelming combat damage, with poison from Karumonix as incidental extra reach.
