Your deck is ok, but it can be much better...95% win rate for me
For more info, see this video from a brazilian youtuber:

I have 2 prismatic Union Attack, so mostly part of time I get 8500 points...Even if I didn't have 2 prismatics card, a deck with 95% win rate and 7000 points per duel is great
I think what he means is like people who don't have Two-headed King Rex and Crawling Dragon? I have do have Rex and I do have dinosaur kingdom but I have the worse of luck when it comes to farm drops. So, I don't have enough to make Dinosaur Kingdom decks -- with that, I have to try and figure out alternative decks when events happen.
