This is more OU than I usually run and I'm pretty open to changes on this team considering I'm not oh-so-happy with it
Okay lets get this started ^_^
Swampert

Relaxed @ Leftovers
252 HP, 252 Def, 4 spatk
-Stealth Rock
-Earthquake
-HP Electric
-Ice Beam
Who doesn't love swampy?
:3 this lovable evolution of Mudkip is a great lead all around. Nice bulk and nice Type coverage. Lets see a Gyarados try to taunt his way out of HP Electric (which is a 2HKO with 0 spDef EVs) Stealth Rock for Entry hazard support. Ice beam and Earthquake for coverage. 306 defense backed with 404 HP makes this thing super physically bulky.
Team Synergy
Grass = Lucario/Latias
Next up is
Rotom

(This is a normal Rotom since I don't have platinum)
Bold @ Leftovers
252 HP Uhh.. I honestly never wrote down these EVs :/
I apologize. 304/114/239/237/190/240
-Wil-O-wisp
-HP Fire
-Thunderbolt
-Thunder Wave
Okay Aside from the fact that I don't know its EVs :/
I do know that it lives all kinds of SD BP Scizor stuff, and it lives +1 Waterfall from Gyara AND OHKO's back with Tbolt. It takes ground/steel/fighting moves like a champ because of its typing and levitate ability. It's also a great status inducer.
Team Synergy
Dark = Lucario/Breloom
Ghost = Lucario/Snorlax
Next comes one of my favorites
Snorlax

@ Leftovers/Thick Fat
168 HP 120 Def 220 spDef
-Body Slam
-Curse
-Crunch
-Rest
This thing us pretty bulky special defense wise. It loves taking fire/Ice moves and letting them bounce off. Then it sets up a few curses and starts the Body slamming.
Any ghost gets in its way gets a Crunch to the face. Rest to keep my sweep going/recover lost HP. This thing is also an awesome status absorber.
Team Synergy
Fighting = Latias/Rotom
Next comes another great :3
Lucario

Adamant @ Choice Scarf
252 attack, 252 speed, 4 HP
-Ice Punch
-Thunder Punch
-Close Combat
-Crunch
Oh man, I prefer this set over the SD Luc, I love the late game sweeping possibilities that this thing has. Ice Punch for Dragons. Thunder Punch for those +1 Gyarados. Close combat for a great stab move with. Crunch for those pesky Ghost types.
Team Synergy
Ground - Latias/Rotom
Fire - Snorlax/Latias/swampert
Fighting - Rotom/Latias
Phew, I'm tired :P two more
Breloom

Adamant @ Toxic Orb
252 Attack 208 speed 48 HP
-Swords Dance
-Seed Bomb
-Spore
-Mach Punch
._. I know Spore is ultra lame but at least I'm not running Sub/Punch amirite?
I love this guy with its STAB Mach Punch. After an SD it can be pretty deadly late game. Seed Bomb for those bulky waters and Spore for sleep to allow me to set up more SDs.
Team Synergy
Fire - Snorlax/Latias/Swampert
Flying - Rotom
Psychic - Latias
Last one :D almost there.
Latias

Timid @ choice scarf
252 speed 252 spatk 4 HP
-Draco Meteor
-Trick
-Surf
-Thunder Bolt
Alright now I don't approve of CM latias ._. just cause its annoying, But scarf is okay :P Draco Meteor is a powerful STAB move that will put a dent in most things. Trick allows me to give my scarf to an unsuspecting opponent. Surf is coverage against ground and fire types and lets me hit steels neutral. Thunderbolt lets me hit those bulky waters and also steels for neutral.
Well that's this new team .-. I know its not so great. That's where you guys come in :D
