Marrow-Gnawer + Ashcoat of the Shadow Swarm
Marrow-Gnawer & Ashcoat of the Shadow Swarm Commander Deck
This deck floods the board with Rats as fast as possible, leveraging Marrow-Gnawer's ability to exponentially multiply your rat count by sacrificing one Rat to generate tokens equal to the total number you control, while Ashcoat of the Shadow Swarm provides consistent card advantage by milling and recursing Rats each end step and turning your growing swarm into a massive combat threat. The primary win condition is an infinite loop between Marrow-Gnawer and Thornbite Staff, which untaps Marrow-Gnawer each time a creature dies, generating unlimited Rat tokens alongside infinite death and sacrifice triggers that can drain opponents through damage-on-death effects. The deck supports this gameplan with heavy cost reduction for black and creature spells, cards like Thrumming Stone that chain Rat Colony copies into play en masse, and sacrifice-payoff enchantments that punish opponents whenever your tokens die.
