I wanted to help people who are struggling with the Mixed gym because I hear and see a lot that people are having a hard time with it so let me know if this works for you and if you need help lets me know and I'm on Pokemon Pets every day so just hit me up.

Every battle starts out with Shiny-Mega-Lugia. Protect to max then use sandstorm and trick to debuff. Switch to Shiny-Mega-Umbreon-Dragon Protect x5 then Hone Claws x5. Baton Pass to Shiny-Mega-Umbreon. Focus Energy x5 then Fake Tears x5. Switch to Shiny-Carvee. Magnet Rise x5. Switch to Shiny Solunawo and sweep every trainer. I used the left path, it's the easiest, to be honest. 

 
ON LEADER: Swap the filler poke for Shiny-Mega-Flygon-Burrower. MAKE SURE IT HAS SURVIVAL ARMOR ( it is necessary to OHKO Hoopa. After that PP Stall Solunawo. Or at least make it so that he can't use psych anymore. Debuff with Lugia, then set up and sweep! I hope this helped.

Thanks for sharing this detailed strategy! Your setup and move sequence for the Mixed Gym are really helpful. I’ll definitely try your approach and make sure to use Shiny-Mega-Flygon-Burrower with Survival Armor as you suggested. I’ll let you know how it goes. Appreciate the tips!

Your EV spreads are well thought out, but remember to tweak them if you find a particular Pokémon lacking in survivability or damage output against specific gym trainers.
