We Shall Inherit

The Underempire

Marrow-Gnawer is my favorite card in MTG and the main reason I started playing back in the day when Champions of Kamigawa came out. Here I've finally incorporated him into a semi-competitive commander deck. The idea of this deck is to spam rat tokens with Marrow-Gnawer's ability and other cards combo off of this by sacrificing rat tokens, removing enemy creatures, increasing your life / decreasing the opponents, and drawing lots of cards.


The general strategy here is pretty straightforward. Try to play on curve and ensure at least 2 other rats are on the battlefield when Marrow-Gnawer comes out on turn 4 / 5. Then the rat doubling begins, and if left unchecked it can quickly snowball by turn 7 - 10.


Primary combos:

Marrow-Gnawer + Thornbite Staff = Infinite Rats. Old school: Plunge into Darkness to sacrifice the rat tokens for infinite life. New school: Ayara, First of Locthwain / Blood Artist / Bastion of Remembrance on the field = infinite life and damage to opponent. Playing The Meathook Massacre can also cause infinite damage to all opponents by killing off the infinite rats. I'm aware of the Tutors that could be included to search for Thornbite Staff, I'm just opting to not always go for the infinite combo as a win-con for this deck. Just an occasional win-con.

Lightning Greaves and Cloak and Dagger make Marrow-Gnawer not targetable and can be equipped immediately for free.

Lightning Greaves and Thousand-Year Elixir give Marrow-Gnawer haste for his activated ability.

Mirkwood Bats activates 1 life loss for every rat Marrow-Gnawer creates, potentially game ending as soon as it's played.

Karumonix, the Rat King can also be a wincon if the Rat Swarm outflanks the opponent due to Poison. With all Rats having Fear from Marrow-Gnawer, it can be surprisingly easy to rack up 10 Poison hits in a single swing.

High Power Rats could also just clobber the opponent from Marrow-Gnawer's Fear if they can't be blocked and there are tons of Rats on the field. Namely Ashcoat of the Shadow Swarm, Persistent Marshstalker, Pestilence Rats, Swarm of Rats.

Coat of Arms and Banner of Kinship can also end the game if one is dropped while there already is a huge rat swarm on the field. If those Ratties are poised and ready to strike. Just watch out because the opponent can benefit from it to, so ideally it should just be used for the winning swing.

Swapped Black Market for Jet Medallion

Reason being: After further playesting, I've noticed additional Ramp would be highly beneficial to getting the 5 drop Commander out as fast as possible, along with sac fodder for him. So having a 2 cost mana rock is far more valuable to that end than a 5 cost sac rock.

Crow_Umbra made some good suggestions for additional Ramp: Warren Soultrader and Phyrexian Tower. I'm cutting Akroma's Memorial for Warren since it's not necessarily a win-con for the deck and is the highest mana cost. Eldrazi Monument also gives flying to all Rats but is easier to remove. I'll play around with it and see if I still want Akroma's or not, just have a feeling it's the least relevant card that I can cut.
