Blaziken - It looks like the idea is use Hone Claws, survive on sash, and then sweep but for gen 6 I don't think this works that well because of the prevalence of SR, priority, etc. Protect instead of Hone Claws and Life Orb might be better. Also, if you're not going to mega evolve it, you definitely want Jolly instead of Adamant. 80 Base Speed isn't that great.
Azumarill - Seems fine. I would like to know why the EVs are spread the way they are, though. I would probably consider running Aqua Jet over Superpower, though. The priority is really good because of how slow Azumarill is and considering that you don't have any speed EVs. Also, Superpower is annoying because after you use it once, you probably have to switch right after. Idk what format this is for, but if Aegislash isn't banned in can come in and set up a SD.
Bisharp - Bisharp is fast enough that you can probably get away with going Jolly + 252 Spe/252 Atk/4 Def. You still won't be that fast, but you'll outspeed enough to justify the change imo. SD over Psycho Cut too, because Psycho Cut only has 70 BP and as far as I can tell it's just to cover Fighting Types, but it probably won't even OHKO anyways and also you can just switch.
Garchomp - Also looks good. Fire Fang > Poison Jab, though. Poison Jab covers fairies but imo Fire Fang is better for hitting Ferrothorn, Aegislash, etc. Some people even run Flamethrower because it hits Ferrothorn even harder but I don't think it's that relevant because it looks like this is just a SR set, not a SD sweeper set.
Venasaur-Mega - Seems fine again. I would still like to know the reasoning behind the EVs, though.
Magnezone - If this is to trap Steel Types, you should definitely give it Magnet Pull. Also, 252 Spe/252 SpA/4 SpD with Choice Scarf is better to trap Steel Types.
