Deck overview

This is a mono-black Rat Colony tribal deck helmed by Marrow-Gnawer, built around two intertwined engines: flooding the board with cheap Rats and converting that board into overwhelming combat damage. The 22 copies of Rat Colony create a hyper-redundant threat base, while Thrumming Stone can turn a single cast into a massive free chain. Marrow-Gnawer himself is the torque of the deck, letting every sacrifice of a Rat create a fresh wave of tokens. The deck can win through fear-evasion combat, an exponential Rats engine with Thornbite Staff, or the independent Sanguine Bond + Exquisite Blood life-drain loop, with Ayara, First of Locthwain and Bontu's Monument adding direct reach. A low average mana value and dense rituals keep the plan fast and consistent.
