Nope. In Fight hurts pretty much every special wall (Blissey, Snorlax, Regice at a pinch) thanks to STAB and SE, even with few Attack EVs.
No as it is mainly a Special Sweeper. You will 70% of the time use FT/GR and In fight is there purely to beat their Special Wall. As the Special Walls have low Defence it doesn't take much attack to scare them off, and Somersault is less about doing damage and more about switching to a counter. Plus it needs lots of Speed so you don' have much room to go so mixed.
It might be depending on your team, but the whole point of the set is to Special Sweep but still be able to beat Blissey.
I need a Good, Moveset, Nature and EVs for a Blaziken.
Yep, good Pokemon. Can Special sweep or spin.

Or go AG with Surf/Ice Beam/Thunderbolt/Grass Rope
Kureseria can have one as a filler. Claydol's pretty good at it. Most pokemon can't afford to have both on one moveset.
