1 ofs are just for some hits for the Restrained Action and can be pretty much whatever you like. Market can also be literally any powerful cards you feel like cheating out with your Worldpyres. The deck is like you mashed together a tradition control deck and a mid range stranger deck and actually plays out pretty consistently. I think you could find room for a 4th Broker, but 3 has felt just right in my games. I don't think this is super competitive but I do have a great win rate and it's a fun deck. Good luck!
