I wasnt here at the time Ou was Blaziken's bitch here (i swear i wouldve loved to tho), but as of right now, i dont see Chuck Norris in pokemon Blaziken getting banned, due to the the slight increase in the amount of checks we have now, namely Azumarill and Talonflame, and its favorite weather getting nerfed, which means now itll have a bit of a harder time going on a sweep.
That is tho, at this stage of the metagame, we cannot predict anything, i must accept i find no mayor problems on BP blaziken but that might be because i havent ever faced it, but if the weather nerf proves to be non-consequential on Blaze, i do find this thing to be a prime candidate for ubers.
Btw i forgot to say Mega Blaziken completely outclasses BLaziken in my eyes, 100 base speed is ridicoulusly huge given Speed Boost, and that added bulk gives him a greater ease of set up that the weather nerf (probably) took out of him.
Rofl i just read through my comment and saw how sleepy i am.
