Not in QC but I want to weigh in a bit.
The Mixed Attacker should honestly not have Flare Blitz as a slash, or at least Second Slash - first of all, that means you have two physical attacks, which creates the issue of not being mixed (all the first slashes don't make it a mixed attacker). Second of all, most Steel-types are physical walls, meaning that you want to hit them hard with Fire Blast. Running Hidden Power Ice as possibly your only Special move means that generic physical walls will have a simple time against you. Though you have an easier time with Jirachi, the recoil damage you suffer from a combination of Flare Blitz and a Life Orb really, really adds up and generally is not worth the trouble.
I also thing Grass Knot should go somewhere in the Mixed Set, or at least be mentioned in AC - OHKOing Gastrodon and doing a lot of damage to weakened Rain teams (suprsingly) is pretty useful. Mach Punch also needs to get a mention, since priority is priority. I have no clue what Thunderpunch is doing there - other than Gyarados nothing is hit harder by Thunderpunch than some other move. I also sorta question U-turn being on the Mixed Attacking set, since it really doesn't add to your coverage, which is really the main point of Mixed Infernape (hit as much as it can as hard as it can), but I'm a bad user of U-turn so idk. We just need to be careful that a "Mixed Attacker" doesn't potentially go all physical.
Also the Choice Scarf set should have a Choice Band as its item and should say "Fire Blast." You also have some odd structuring errors including Other Options being under Choice Band, Checks and Counters appearing not in the correct area, and the nonexistant "Teammates and Counters" section.
