Best Special Move for Blaziken? (Non-Comp)

[LeoTheShrugger77]

I want to put a move that deals special type damage on my Blaziken, to take advantage of its Sp. Atk stat. I thought Focus Blast, but it has very little PP, although I am inclined to a Fighting type move, since I wish to focus on the Fighting type, for STAB, and I already have Blaze Kick. Fire type or coverage suggestions are acceptable, too, I am just more inclined to Fighting type STAB.

 

Moveset I am building towards:

Blaze Kick

Sky Uppercut

Brave Bird

(Special move)

Grass knot for coverage, flamethrower for STAB.

I don't know if Blaziken learns Aura sphere, but if it does, you can get the TM for it at any mart.
