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 5 / 6. Then the rat doubling begins, and if left unchecked it can quickly snowball by turn 9 or 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. 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.

Updates Add

In: Revenge of the Rats Out: Pitiless Plunderer

Reasoning: The Plunderer hasn't seemed to be very impactful, typically only one sac per turn is only one Treasure. If board wiped that could be good, unless it's wiping everything. The new Sorcery serves a similar comeback role, but it is not reliant on the type of wipe (except Exile) and is the same converted mana cost. It will also help come back giving more fodder for Marrow-Gnawer to start doubling again, and it can even be used twice.

Also added Swarmyard Massacre replacing Valley Rotcaller

Reasoning: Valley Rotcaller has a good effect for this deck, however its creature type does not synergize, and in order for it to get value from its effect, it has to attack and will most likely die while doing so since it does not benefit from Marrow-Gnawer's Fear. Swarmyard Massacre is an amazing card for this deck that I initially overlooked since it creates two Squirrel tokens. However the board wipe effect is even better than Crippling Fear - for 1 more mana and with only 1 rat on the board it has the same effect. If there is a swarm of rats then it effectively board wipes enemy creatures only. It seems like it could be better in general, so going to try it out.
