"Set Commander" button not appearing

{"ops":[{"insert":"Trying to create a new Commander deck, I've created on on here before and I can't figure out what I did different. I know the deck is set as a commander deck, but it wont let me set any legendries as the commander. Does anyone know how to fix this?\n\nEdit: Additionally, looks like it won't save the deck. I started creating the deck, then made this post, went back to my decks and it doesn't exist... tried making it 3 times now.\n\nEdit: No Idea what I was doing before, but I got it to work. \n"}]}
