I need help improving this Dragonite V ADP Deck

I need help improving this Dragonite V/ADP Deck. I want a very fast set-up that allows me to 1HKO bassically everything in the game. With ADP's GX Attack, Choice Belt and Kukui I can do 330 to Pokemon Vs and 300 to non-Pokemon V. This takes out every pokemon besides for Snorlax VMAX, Copperajah VMAX, and Eternatus VMAX. I also think that using Acerola to preserve prize cards in combination with Zeraora and the two godly setup Dragonites will take this deck 1 step further. How can I improve upon this deck?
