I swear that when it comes to EV's and IV's I'm still a novice, but why did you give to Blaziken a nature that lowered its Sp. Def and increased its Sp. Atk, which isn't even Blaziken's forte?
Besides isn't Overheat a bit too risky? I think that Blaze kick or Flare Blitz is enough for Blaziken...Shadow claw as you said, should be a better option for type coverage.
Moreover, I would teach it again Hi jump kick; it is more powerful than Sky uppercut and they pretty much have the same precision.
Just saying; after al you're free to do what you want with your Pokèmon
After MegaEvolving, it has a base 130 Sp.Attack.
I think it could be useful for the physical walls trying to switch in. Also, I don't want to lose half my HP/kill myself if someone decides to use Protect or send out a Ghost, so that's why I don't run HJK or, to a lesser extent, Flare Blitz.
