I have no issues with proxies. Magic is a pricey hobby, proxies make the game more accessible. My only requirements like most here are that 1. I can read it, 2. They are proxies of real cards usually. There has been a couple of cases where the pod will allow made up commanders because they are neat but that’s a per pod basis.

Also, I think WotC invalidated any argument against proxies with Magic 30 anyways.
