This deck's strategy is very straight forward, win by swinging with Rats! The strategy is mainly supported by card draw. Due to the threat Marrow-Gnawer and Rat Colonies pose there will be plenty of removal and board wipes. Keeping your hand full of Rats even in the late game is this decks strong suit.
This decks main objective is to power up the Rat Colonies quickly and swing for the win. Resolving Marrow-Gnawer after filling the board with Rat Colonies is the primary win condition. However, cards like Coat of Arms, Thornbite Staff and Thrumming Stone are the powerhouses of this deck. Resolving any one of these and keeping it even for a single turn cycle could end the game.

This decks secondary objective is purely a support objective, card draw. Instead of putting extra resources into removal or protection from removal, the deck focuses on filling/refilling your hand. Due to the large amount of card draw in this deck, refilling your hand and resolving another entire rat army again is a cinch. Here is a list of some of the decks standout card draw engines:

Phyrexian Arena

Secret Salvage

Vanquisher's Banner


Species Specialist

Grim Haruspex

Disciple of Bolas


This deck is supported by consistent ramp and some disruption. The ramp is very straight forward; mana rocks and some colorless land ramp with Myriad Landscape, Wayfarer's Bauble, and Sword of the Animist.

Disruption: Decree of Pain is a board wipe that doesn't just even the playing field, but puts you far ahead of the rest. Piper of the Swarm and Throat Slitter are fun and flavorful ways to remove problematic creatures from opponents boards. Ink-Eyes, Servant of Oni and Nezumi Graverobber are similarly flavorful cards that allow you to grab large threats from other players graveyards.

I was purposeful about building the deck in a way that Marrow-Gnawer is not always needed to acquire victory, but I do understand how powerful of a commander he is for this deck. I have included cards like Lightning Greaves and Swiftfoot Boots in order to protect him and take advantage of his powerful abilities.

Also, I do understand how many powerful game ending combos could be inserted into this deck, it just wasn't the direction I wanted to take. However, I did relent and include Thornbite Staff into this deck list. My main goal is to use it to power up my rats and swing for an easy victory early in the game, but I can't say I would be disappointed in resolving a card like Ayara, First of Locthwain before Thornbite Staff is activated.
