jk. Actually, good thing you're not one of those Mirror Wall nerds. Tbh, I think the issue is ppl have gotten used to meta decks, especially decks like yours which is almost exactly the same as the sample deck in this site.
I suggest carrying Trap Jammer or anything to counter mirror matches. Maybe Magic Jammer to counter Twister and Order to Change.
Hey Natsu916. There is an issue with your current Dino deck and I see now why you can't reach KoG. Check out the modified version of the Dino Deck that I talk about here: https://redd.it/5uruyo
This has got me to KoG every single time, very quickly. Hope it'll help you too!
