>>171833391. Blaziken doesn't set up on Garchomp. If it is, it's Balloon Blaziken, and then it's going to set up on you anyways because Outrage doesn't even come close to killing. Remember, you have to switch into Blaziken. It's going to make opportunities to set-up on Pokemon that can't kill it.
2. +2 HJK OHKOs Garchomp. Even from normal Blaziken.
Kyogre wouldn't be Ubers if everyone had the IQ of a potato. Blaziken is absolutely trivial to outplay your opponent with, and even a single Pokemon on their team being set-up fodder basically means they lose.
