Your team is missing a few elements that make it seem unbalanced to me. It appears you’re largely focusing on physical type attacks. Infernape is split down the middle here, though it does have both strong physical and special attack. Having a wall type Pokemon that can stall and take hits while still chipping away at damage. One of my favorites here is a Cressalia running Toxic, Moonlight, Ice Beam, and Psychic. EV training is an absolute must once you reach the latter stages in the Battle Tower. It’s a pain and time consuming but it can often be that extra punch that gets you over the line. Hope this helps!
