Deck overview

This is a mono-black Rat tribal swarm deck helmed by Marrow-Gnawer, built to flood the battlefield with cheap Rat Colony copies and token generators, then close the game through overwhelming combat damage backed by tribal anthems and black drain effects. The primary engine is the 20x Rat Colony package, which turns every draw into board presence and enables the explosive Thrumming Stone ripple chain that casts every copy for free. Marrow-Gnawer's activated ability converts a single rat into a burst of tokens, while Ayara, First of Locthwain and Gray Merchant of Asphodel provide a life-drain secondary axis that punishes opponents even through board stalls. The deck leans on tribal pump (Coat of Arms, Door of Destinies, Bad Moon) and a modest recursion suite (Whip of Erebos, Bloodline Bidding) to grind through removal, with the Thrumming Stone line serving as the deck's one true combo finish.
