Never used Blaziken myself but there is this:

-High Jump Kick
4 HP, 252 Sp Attack, 252 Speed
248 HP, 252 Attack, 10 Sp Def
Obviously, the main attraction of this team is Blaziken. I decided to try Blaziken after seeing Peterko's Cloyster streak and Carl's streak with his Lum-DD-Multiscale Dragonite, which inspired me to try to find my own "one and done" sweeper (who sets up in 1 turn and proceeds to sweep the opponent). Blaziken is really cool in that in one turn, he goes from mediocre power and speed with unreliable-accuracy moves to solid power, fast speed, and above 100% accuracy moves. After settig up and KO'ing the opponents lead, Blaziken becomes somewhat of a runaway train with 2 Speed boosts and counting. Sometimes I think an Adamant nature could be better, but when I lost, it really wouldnt have helped.
One problem I found with Blaziken is that it pretty much needs to set up in order to preform greatly, whereas Dragonite can still dominate without a DD.
I think Blaziken could do better on a different team, I really just slapped it together quickly to see if Blaziken was any good, but I loved its synergy with Latios. Thunder Wave users could be problematic, since Blaziken absolutely cannot be paralyzed, so I had to usually go to Scizor to take the TWave xD.
Maybe that will give you some insight to how it performs? Another issue with Blaziken is simply that it is hard to obtain it legally since hacks can't be added to the list. It was only released in Japan as a male-exclusive event (i.e. you can't breed more of them) so you probably won't get your hands on a legal one unless you know someone with one.
Not that I'm questioning how Stay Gold got his :p
Anyway, I haven't been play much subway lately, but I did try the Emerald Battle Factory, which was a complete failure! It's wierd because the battles seem to be a lot easier than in the 4th gen equivalent but I end up losing to hax. I guess the fact that everything seems to have a hax item (Focus Band can go to hell) makes all the difference...

I'm a tad late here but I just wanted to say that I like the way Hitmonlee is used here. Normally his lower speed (and lack of secondary STAB) make Infernape the better choice, but Tailwind helps offset the speed issue, and Infernape's Fire attacks have issues (Flare Blitz breaks sash, Overheat is inaccurate and lowers special attack, and Flamethrower is just weak without Blaze, as is Fire Punch unless you have Iron Fist). Meanwhile, Hitmonlee gets more power and Limber is great considering you will want to Fake Out Electric types, who love blasting Tornadus.
I still prefer Infernape because its higher speed does mean I don't need to use Tailwind against as many things, but Hitmonlee is still cool!
