Ahh yes. I just finished the latest version of it. Took a while to do despite it being released a while ago because of my backlog of Pokemon Fangames.
Just the witty banter of your character makes this a must play game imo lol
The elimination tournament matches are a good replacement for gyms. Especially for those who always ask for a Pokemon game to be a bit different but don't like the Battle Trials in Alola. Makes it feel like you are in the preliminaries of the 1st Gen Anime Pokemon League.
I don't have any, but if you happen to be searching for one, I believe you can find it where you fight the Gargantuan Steelix in Tanzan Mountain.
Hope this is not spoilers
