Deck overview

This deck is a mono-black Rat tribal swarm strategy commanded by Marrow-Gnawer. Its primary plan focuses on establishing early board presence with redundant copies of Rat Colony, deploying the commander on Turn 5, and activating its ability on Turn 6 to double the swarm while granting fear. The deck achieves high operational consistency within its creature package thanks to 15 identical Rat Colony cards and tribal payoffs like Ashcoat of the Shadow Swarm and Karumonix, the Rat King. Explosive ceiling lines exist through Thrumming Stone ripples and Thornbite Staff loops, though the lack of universal tutors keeps these lines occasional rather than guaranteed. The deck operates primarily at sorcery speed and invests heavily in creature permanents, making it susceptible to board sweepers and targeted removal. However, strong mass recursion spells ensure the swarm can rebuild and finish games across mid-game combat steps.
