I have a shiny Minior that I bred for that I always use competitively (I think it may be my favourite gen 7 Pokemon!) and I was kinda upset that I couldn't use it but the whole retro theme is still entertaining! (I hate running into snorlaxes tho, they just wont go d o w n)
I remember Elesa's emolga from gen 5 always annoyed me. Volt switch is the bane of my LIFE!
I was getting a little bit worried in the middle of the battle with that tyranitar tho >~<
I had to get the hidden abilities of some of my pokemon so I had to go back to X and Alpha Sapphire to find them, then transfer them up and then get IV breeding!
You did really good as well! Just remember that you still have a chance even if you lost the first round
