I have recently gotten swept by a Blaziken with Air Balloon. I must concur that it is quite easy for it to sweep and could be the best set. Bulky waters that stop this Blaziken are much fewer than those for his other sets because this Ken is definitely going to have +2 and 3 attacks by the time they switch in. It's extremely effective and has very few counters. Although like you stated plenty of Pokemon are going to use U-turn on it which is its only down side in this meta-game. In sand Excadrill still would out play if the opponent thinks the opponent will switch, but Ken users know this set doesn't need protect and should kill him on site. This would on a positive note leave Ken hurt by Return/Rockslide damage and cause him to only gain +1 speed and nothing else. In sun it's a completely different game however, because now water types are not doing major damage, ground types aren't temporarily and Ken has a fire power boost. Only full health Dragonite and Gyarados have a chance at defeating this Blaziken in my opinion.
