Changeling heavy horsemanship

{"ops":[{"insert":"Hi again people, appreciate all of your help and I've fixed or acquired most decks I talked about in here.\n\n"},{"attributes":{"background":"var(--light-background)","color":"var(--color)"},"insert":"I was looking into horsemanship and there wasn't a huge selection I could go off of. Though there were a couple cards that gave a certain creature type horsemanship for a span of time. Hence changeling creatures."},{"insert":"\n\nI was wondering what commander could fill the role of signing up enough colors for it to work decently while still being a help to the deck in general. I do not play cEDH though I like focus decks that can have a strong presence on the board (that's why I would like to not be blocked). \n\nIf you have ideas of must include cards in the 99 (or 98 if partner) then that would be helpful too.\n\nThank you for any advice you have, I'm actually invested on this idea.\n"}]}
