So I did some searching on some ranking websites and decided to filter out partner commanders because they are obviously underplayed without a partner, because why would you do that, and also have some more niche combinations of partners, and came up with this list. Some good that came out of this is some really cheap really good commanders, however, most of the possible commanders are just from the same set and have similar abilities, and I can only assume that either horsemanship is slightly too complicated and niche for new players to want to play with or the fact that the cards in question are for some reason really expensive is the turn-off. Obviously, some are here just because they're bad or too specific.
