Deck overview

This mono-black deck executes a dedicated Rat tribal swarm strategy centered on Marrow-Gnawer. The early game focuses on deploying redundant threats like Relentless Rats and Rat Colony alongside steady 2- and 3-mana ramp artifacts. Casting Marrow-Gnawer on Turn 5 sets up an operational token engine on Turn 6, using its tap ability to sacrifice one Rat and double the remaining swarm while granting fear to the entire board. The deck accelerates lethal pressure through exponential token growth, anthems like Ashcoat of the Shadow Swarm, and life-drain payoffs including Valley Rotcaller, Mirkwood Bats, and Gruesome Fate. The list features high functional redundancy in its creature core, though its reliance on combat damage over multiple turns and sorcery-speed removal leaves it susceptible to well-timed sweepers and fast combo strategies.
