Yugioh- fix my arcana knight joker deck?

This deck is interesting, it looks like it would be successful. I'm not sure what you are asking in the question but to improve it I would find a friend with a decent deck and duel them. As you duel a few times the problems with the deck will stand out to you and you will see what cards aren't working for you and which ones are. Check and see if Royal Decree is limited or not, I'm not sure with the new September list. Other than that the deck looks good!
