2 of your attacking moves are physical but you use a nature that takes away attack? Why?
Flame Charge is bad because you have speed boost, why do you need a weak move like flame charge? If you really want a move that isn't Flare Blitz, Blaze Kick is a thing.
Solar Beam goes off Blaziken's lower Special Attack stat, and if you don't have the opportunity to set up Sunny Day first, also worthless.
Sunny Day requires either lots of bulk or be a suicide lead to pull off. Blaziken has neither of these. You're better of just using Sword's Dance.
High Jump Kick, although riskier, is still preferred because of it's ability to damage incredibly bulky threats better than semi-power moves like Sky Uppercut.
