Deck overview

This mono-black tribal deck leverages Marrow-Gnawer alongside 25 copies of Rat Colony to execute an explosive go-wide strategy. The primary game plan deploys early Rats to build board presence, then casts Marrow-Gnawer to double the swarm and grant universal fear evasion. The list features a potent two-card infinite combo with Thornbite Staff, which untaps Marrow-Gnawer whenever a sacrificed Rat dies to create arbitrarily large numbers of Rat tokens. Alternatively, Thrumming Stone allows a single Rat Colony cast to ripple through the entire library, putting dozens of high-power creatures onto the battlefield in one turn. Mana acceleration from Cabal Coffers and Three Tree City fuels high-cost spells and rapid rebuilding. While vulnerable to exile sweepers and lacking stack interaction, the deck maintains excellent resilience through mass reanimation spells like Patriarch's Bidding and Living Death.
