Bracket: 3

Deck overview

A mono-black rat swarm deck that wins by stacking poison counters through toxic and infect while grinding value off creature deaths. Karumonix is the command-zone lord and card-advantage piece: it gives every other Rat toxic 1 and filters the top five cards for more rats. The deck builds wide boards with Marrow-Gnawer, Lord Skitter, Pack Rat, and Chittering Witch, then either attacks with multiple poisonous sources or converts dying rats into life loss via Blood Artist, Zulaport Cutthroat, and Bastion of Remembrance. Proliferate effects such as Contagion Clasp and Karn's Bastion accelerate the ten-poison clock and make the finish less combat-dependent.
