Un-ban
Blaziken: We're at the point in the B/W metagame where we have learned to build our team to counter or check high powered threats and keep playing. Excadrill, Thundurus, and latios are examples of pokemon who people were initially freaked out about, but then simply learned to carry checks or counters to them.
Why is it then, that we were so quick to ban a pokemon with more checks and counters than any of the above three pokemon I mentioned? I feel as though blaziken should be brought down for a retest, as his ban just MIGHT have been a bit too hasty.
The reasoning for banning blaziken was due to speed boost and the high jump kick buff. Thanks to speed boost, you couldn't revenge kill blaziken as easily while he steamrolled half of your team with a base 130 power attack. It makes sense that you wouldn't be able to easily outspeed and revenge kill a pokemon once he got faster and faster, but...
He only starts off at base 80 speed. And in order to get strong enough to threaten the majority of the metagame after a swords' dance, he needs an adamant nature. After a +1 boost, blaziken is getting outsped and revenged by any scarf user with base 80 speed or more and a speed boosting nature. As far as weather sweepers go, blaziken is outsped by all of them after a +1, and is still outsped by excadrill, lilligant, and the rare timid venusaur.
Now let's say that blaziken is running protect. He comes in on something he can kill or force out, like blissey. He uses swords' dance as you switch to your revenger. Blaziken then uses protect to outspeed said revenger. At this point, you know that he's only running two attacks. Most likely Hi jump kick and flare blitz/coverage move.
With Hi jump Kick and Flare blitz, blaziken is walled by the following OU pokemon: Gyarados, Dragonite, Latios, Latias, Jellicient, Chandelure. If you look to the other tiers, there are options like Slowbro, who was his most popular counter. Of course, blaziken can easily switch out of said pokemon, resetting speed boost and being forced to set up all over again. This is no different then when Excadrill is forced to switch out of Gliscor or a conkeldurr who came in to revenge him.
Another big issue against blaziken is rain. Good rain teams can simply run fighting resistant pokemon to eliminate the threat of blaziken altogether. Gliscor may lose to Mixken (who loses to a ton of stuff), but he will never lose to blaziken in the rain. Of course, one could easily counteract this by running blaziken under sunlight. However, sunlight is much harder to keep up consistently than rain and sand. This is easier said than done. Shame about non-weather teams though, but that is more attributed to sunlight than it is to blaziken himself.
Much like excadrill, the pokemon who deal with blaziken all have application in OU and are not used for the sole purpose of taking blaziken down.
I'm not supposed to argue in the nominations thread, so I'm posting my response to this here.
Sun is hard to keep up without Blaziken. With Blaziken, it's not hard at all. This is what Adamant Life Orb Hi Jump Kick does to specs/scarf Politoed: 113% - 133.2%
And that's before Swords Dance. So Politoed is not switching in to say the least.
If he runs a physically defensive 252/252+ set, which he will be forced to, he takes 64.3% - 76%. So he can switch in once, next time, he's dead.
TTar, is like, 2HKO'd after a 3 layers of spikes and stealth rock obviously.
Now if sun is up, this is what happens to your list of counters. All of these calcs are +2 Adamant Life Orb Flare Blitz.
Gyarados: RestTalk (248/252+): 63.1% - 74.3%. With Stealth Rock, and a bit of prior damage, he's dead.
Bulky DD (156/96): 86.8% - 102.2%. Guaranteed death after Stealth Rock
I'm sure I don't need to show you Offensive DD...
And no, I didn't forget to factor in Intimidate.
Dragonite: Choice Band (0/0): 127.2% - 150.2%. That's without Multiscale, but with Stealth Rock, this Dragonite is pretty dead.
Bulky DD (252/0): 106.5% - 125.6%. Dead after Stealth Rock. This is Dragonite's most physically bulky spread.
Latias: Calm Mind (252/0): 118.7% - 139.6%. Counter of the year.
Latios is frailer so I'm not even gonna bother with that.
Jellicent: Utility Counter (248/216+): 91.6% - 107.7%. Dead after Stealth Rock.
Chandelure: Anything (???/???): 0%-0%. Dead after a full field of hazards switching in twice!!!
In all seriousness though this is the best counter.
Slowbro: 67.8% - 79.7%. Slowbro is a badass. Not a wall, but he does win.
He kills almost all his 'counters'. Without any random coverage moves.
So tldr; Blaziken makes keeping sun up easy since Politoed and Ttar can not switch into him unless they want to die, and then when sun is up he kills everything except for Slowbro and Chandelure. Please don't unban him.
