Deck overview

This deck is a mono-black Rat tribal strategy led by Karumonix, the Rat King. It leverages Karumonix's static ability to give all friendly Rats toxic 1, turning inexpensive rodents into lethal poison threats. The deck deploys early creatures like Rat Colony, Pack Rat, and Changeling Outcast before casting Karumonix on Turn 3. Karumonix refills the hand by digging five cards deep for additional Rats while immediately enabling poison pressure. Once opponents receive their initial poison counters, the deck accelerates the clock using evasion effects like Cover of Darkness and Piper of the Swarm, backed by proliferate spells like Phyresis Outbreak, Vraska's Fall, and Drown in Ichor. The plan eliminates opponents by reaching 10 poison counters rather than dealing 40 combat damage per player. While the strategy deploys poison rapidly, it remains vulnerable to sweepers and lacks stack interaction or non-creature removal.
