This is a Commander deck I built a very long time ago and haven't updated since 2019. I will NOT split this up into its constituent parts.

This deck originally started as an attempt to build a rats tribal deck without resorting to Relentless Rats (I was having a hard time finding them in large groups at the time, and Thrumming Stone was worth like ten times what it is NOW at the time) -- so instead I went with something more combo-oriented. It uses an odd combo that involves a Bog Initiate (can freely turn your mana black) in a mono-black deck (it allows you to sacrifice certain creatures with Ashnod's Altar and replay them immediately for infinite sacrifices/creatures entering the battlefield/etc.) because I'd wanted to do something with it for a while and I saw an opportunity considering the limitations I put on myself. After I built the initial version, Dominaria released and it contained Rat Colony; I chose to just add those as I got them, but I never got very many.

Assume all cards in the deck are in lightly played condition and in English language unless otherwise noted in deck list.

If you have any questions, feel free to ask. All sales final.
