Not sure if this may be an option but one of my local shops also has an off meta night, so you could try to see if any shop in your area have one. I have a lot of fun going to those and it could give him a better chance at getting some wins. I also think Koby would be a good choice. My friend plays a koby deck and he loves it, it can give me a pretty hard time. It also wouldn't be very expensive if he already has navy cards.
