Surprising Legendaries (OU RMT)
Heatran@Shuca
Naïve
4 HP / 252 Sp Atk / 252 Spe
~ Stealth Rock
~ Fire Blast
~ Earth Power
~ Explosion
Standard Leadtran. Not much to say about, can deal with Blissey/Snorlax with Explosion. Sometimes I use sash over Shuca.
Bronzong@Leftovers
Sassy
252 HP / 58 Atk / 180 Def / 20 Sp Def
~ Calm Mind
~ Gyro Ball
~ Hidden Power Fire
~ Hypnosis/EQ
Surprise #1. This Bronzong is just awesome. After 1 CM he can OHKO Scizor and Forrotress with HP Fire. It takes physycal hits like a beast and Special too after some 2 CMs. It has a chance to 2HKO the SteelTrapper Magnezone after one CM, but that's slim. 2 CM's ensure a 2HKO and that will make him take his hits even better too. CM works surprisingly well becuase Zong almost ALLWAYS has a chance to use it. Relaxed is another option, haven't tested that.
Celebi@Leftovers
Timid
252 HP / 80 Def / 176 Spe
~ Calm Mind
~ Psychic
~ Recover
~ Baton Pass
The standard CM passer. This supports Heatran, Zapdos, Bronzong and Suicune. Ever seen Heatran and Zapdos after a boost or two? Boy, you should get the hell outta there when you spot it. They can become extremely hard to take down. It's also my Breloom counter and makes a fine sweeper after a CM or two, except for Darks/Steels/Psychos.
Zapdos@Life Orb
Timid
4 HP / 252 Sp. Atk / 252 Spe
~ HP Grass
~ Thundebolt
~ Roost
~ Heat Wave
Standard LO Zapdos, HP Grass is to take out Swampert, because it's just so annoying if I don't carry it. Thunderbolt is the regular STAB move and Roost to heal/deflect Ice attacks. Heat Wave is for those stupid steals who think they can continue their rampage if Zong has fallen. It's also one of my favorite sweepers. CM makes it even deadlier.
Suicune@Leftovers
Bold
252 HP / 252 Def / 4 Spe
~ Surf
~ Rest
~ Calm Mind
~ Sleep Talk
The standard Crocune. Monotype attacking is that bad after a few CMs. I could run Roar over Sleep Talk to bust other stat-uppers. I love this thing.
Mesprit@Choice Scarf
Jolly
80 HP / 252 Atk / 176 Spe
~ Thunder Punch
~ Ice Punch
~ Zen Headbutt
~ U-Turn
Surprise #2. With the Platinum update, physical Mesprit is a lot more viable then in the old D/P. These EVs make it outspeed base 130 Speed pokémon with a +speed nature. U-Turn OHKO's Weavile, Ice Punch is my Dragon Counter, Thunderpunch my Gyarados counter and other flying stuff. Zen Headbutt is a strong STAB attack which makes it even more dangerous. U-Turn is just to get the hell out of there if he can't do anything.
Adamant is an option to boost my Attack, but I'll lose the speed advantage to the 130's. I could also max speed and slap a Band on it, but I like it's high speed.
OU's (I hope these are all of them):
Machamp - Mesprit can handle him, Zapdos will finish if necessairy.
Lucario - Zapdos/Zong/Tran.
Metagross - Zapdos/Zong/Tran.
Scizor - Zapdos/Zong/Tran.
Breloom - Zapdos/Celebi/Mesprit.
Zapdos - Mesprit/Suicune/Zong.
Azelf - Mesprit+Suicune.
Magnezone - Zapdos/Tran(non-scarf that is)/Zong.
Aerodactyl - Zapdos/Mesprit.
Alakazam - Mesprit+Zong/Cune.
Gengar - Mesprit.
Celebi - Mesprit+Zapdos/Mesprit+Zong/Mesprit+Tran.
Gyarados - Zapdos/Mesprit.
Dragons - Mesprit.
Gliscor - Mesprit/Cune/Sometimes Zapdos.
Dugtrio - Mesprit/Zapdos/Cune.
Kingdra - I just charge it at full power with anything but Tran.
Blissey - Mesprit+Tran/Tran/Zong after CM'ing/Cune after CM'ing.
Snorlax - Can be tough, Tran/Zong after CM'ing/Cune after CM'ing.
Tyranitar - Mesprit+Zong/Mesprit+Cune.
Hippowdon - Cune/Zapdos.
Infernape - Mesprit/Cune/Zapdos.
Swampert - Zapdos.
Dusknoir - Don't have an answer to this really, usually wear it down with Cune.
Mamoswine - Zapdos(watch out for CB Ice Shard though)/Cune/Zong.
Heracross - Mesprit/Zapdos/Bronzong to an extend.
Latias - This bitch shouldn't be OU in the first place v.v Mesprit+booster to try and deal with it if it is too hard.
Tentacruel - Mesprit/Zapdos/Zong if carrying EQ then.
Skarmory - Zapdos/Mesprit/Cune/Zong/Tran.
Rhyperior - Zapdos/Cune.
Jirachi - Tough one, Zapdos/Tran/Cune should do the trick.
Jolteon - Not that counterable. Mesprit can wear it down with Suicune. or Tran if he's still alive.
Ninjask - Rocks should take care of this or else Zapdos/Tran.
Empoleon - Zapdos/Tran could weaken a bit with EP.
Elektivire - Tran is my best guess, luckaly, it's not used that much anymore.
Donphan - Cune/Zapdos/Celebi.
Cresselia - Like Latias. A real pain. This requires a (lot of) combo(s). Mesprit+Celebi->Zapdos does it a lot of times.
Porygon-Z - Shut down by Suicune/Zong completely.
Heatran - Suicune/Heatran/Zapdos after a boost.
Bronzong - Heatran/Zapdos/Bronzong/Suicune
Note to where I've put "Mesprit+???".
That means Mesprit U-Turns to take a big chunk of health away to let something else switch in quite safely and kill it afterwards.
Celebi isn't used that much, but it's CM passing is worth gold on this team. Even Mesprit can profit from that to take special hits good.
I think that was all.
EDIT: Yay, namechange n.n
I seem to have a little trouble with some speed raisers and Cursing pokémon. But not much. Unless you guys find something else.
Sidenote:
DON'T START ABOUT ROTOM-A. HE'S NOT MADE FOR WIFI AND I WON'T EXCEPT HIM THERE SO DON'T POST NOTHING ABOUT IT.
I really hate the fact he's usable on shoddy.
Thank you.
