Deck overview

This deck is a mono-black Rat tribal strategy helmed by Karumonix, the Rat King. The game plan revolves around flooding the board with low-cost Rats during the opening turns, casting Karumonix on Turn 3 to replenish the hand with additional Rats, and granting the entire swarm toxic 1. Starting on Turn 4, the deck begins applying poison counters via combat damage and infect creatures like Ichor Rats. Mid-game pressure is sustained by token multipliers such as Marrow-Gnawer and Pack Rat, backed by proliferate engines like Contagion Clasp, Contagion Engine, and Vraska, Betrayal's Sting to tick up poison counters without needing to bypass clogged ground defenses. The deck features modest discard packages to disrupt opponents' hands, though its low overall mana velocity and vulnerability to sweepers keep its operational ceiling grounded in casual-focused pods.
