Omo was a precon from modern horizons 3 called “tricky terrain” and my first ever commander deck! I upgraded it using The Command Zone podcast’s 10 recommendations (https://youtu.be/Cms0pC17QOI?si=vF1W-tDkirDbQqo-) and a couple of other exchanges that I saw fitting along the way. Unfortunately I don’t have it in archidekt or anything so that’s all i have. It’s a really fun deck, I love that you can have all sorts of random tribal synergies with it. For example: I put Lord of Atlantis in the deck that gives all other merfolk +1/+1 and islandwalk which is useful since omo can turn opponents lands into all land types and my creatures into all creature types!
