I am assuming that you are still working on this since atm the layout is a little jarring. For example you have the OO section and the Checks and Counters section right after CB rather than at the bottom.
Just a few quick points
Infernape completely hates Politoed and bulky water types, like Tenacruel, Gastrodon, and Quasure.
Its true that Infernape dislikes these pokemon (Tentacruel especially) but you could mention that Gastrodon and Politoed (and o.k, Quagsire too), will HATE switching into a CB Close Combat as it does far too much for their liking.
Tentacruel and Rotom-W are great counters to Infernape
Again, Rotom-W cannot really switch in and eat a LO or CB backed CC. A Counter has to switch in and not really give a shit at any damage it might take switching in.
-Move Fire Blast to first slash on Mixed, recoil is a bitch and LO is wearing you down even more.
-Add Mach Punch to the AC of Mixed. Its good vs Terrakion (since you would otherwise have to risk the speed tie or hope its not scarfed)
- NP and SD need to be mentioned in OO at least. NP Infernape used to be a terror under sunlight but it does struggle to set up in this face paced metagame (and especially with rain so dominant).
In terms of set order I prolly like CB first since I have better success with it but Mixed is more common. Can other QC members weigh in here so we can decide the set order?
