Hey this is my first RMT so it probably isn't that good especially since I suck at team building. Please be constructive in your response and please help improve the team.
Jirachi @Damp Rock
Serene Grace
EV's: 142 HP, 252 Atk, 128 Spd.
Nature-Jolly
-Rain Dance
-Stealth Rocks
-Iron Head
-U-Turn
Jirachi is a great pokemon to set up for a Rain Dance team. Its bulkyness allows it to take hits while it sets up. Basically sets up both Rain Dance and Steath Rocks then flinch hax's the crap out of the other pokemon or just u-turn the hell out of there. It has enough EV's in speed to outspeed neutral base 95's. Stops both Abomasnow and Tyranitar in their tracks and gets rid of both of their weather conditions
Omastar @Life Orb
Swift Swim EV's: 6 HP, 252 Atk, 252 Spd.
Nature-Modest
-Surf
-Hidden Power Electric
-Ice Beam
-Earth Power
This thing shines in the rain. Surf does a crap load to pokemon that aren't ready for such a massive attack under rain. Hidden Power Electric takes care of Gyarados and other water pokemon that think they can easily come into it. Ice Beam is for the obvious dragons out there except for Kingdra. Earth Power takes out any other pokemon that comes in its way.
Kingdra @Leftovers
Swift Swim
EV's: 182 HP, 252 Atk, 76 Spd.
Nature-Adamant
-Rain Dance
-Dragon Dance
-Waterfall
-Outrage
With so much bulk under its belt why not double dance. I was thinking maybe impish and run a defensive spread but Adamant supports the raw power that Waterfall can do under rain with stab. Very easy to switch in since it only has one weakness and I doubt anyone would switch in Kingdra into a dragon pokemon. Don't know weather to keep lefty's or give it Damp Rock for Rain Dance support.
Ludicolo @Leftovers
Rain Dish
EV's: 204 HP, 106 Def, 76 Sp. Atk, 124 Sp.Def
Nature-Calm
-Rain Dance
-Leech Seed
-Toxic
-Grass Knot
This mexican duck thing is freaking sexy when it comes to stalling/annoying. It's also my third Rain Dance set upper. Toxic then leech seed which forces a switch and if you predict well enough you can get a toxic on the switch in. Leftovers+Rain Dish+Leech Seed= Almost undefeated unless a Scizor comes in and X-Scissors or U-Turns on his ass.
Dragonite @Leftovers
Inner Focus
EV's: 248 HP, 54 Spd, 208 Sp.Def
Nature-Calm
-Dragon Pulse
-Heal Bell
-Thunder Wave
-Roost
I fell in love with this set when I saw RL's thread on Dragonite. I decided to use it and it works so well with this team. The second more than one pokemon has a damn status problem this beauty comes in and saves the day with heal bell. Thunder wave stops many sweepers in there tracks as this bulky beast takes their hits. Not only that Roost off any damage and hope for the para hax to kick in anytime soon.
Electivire @Expert Belt
Motor Drive
EV's: 76 Atk, 180 Spd. , 252 Sp.Atk
Nature-Mild
-Thunder
-Cross Chop
-Hidden Power Grass
-Ice Punch
There is only one pokemon weak to electric on my team which is Omastar but there seem to be so many pokemon running thunder wave nowadays. Cross Chop deals with blissey which seems to be a major problem on my team and will probably switch into this once they see a special move on this. Makes a great revenge killer once Motor Drive kicks in.

Problems
- I don't know why I have problems with scizor on this team. Possibly because their are no fire moves on the team
- Vaporeon and Celebi wall the crap out of this team. Omastar and Electivire seem to be the only one's on the team that can deal with them.
- Once Evire and Kingdra are gone a sp.walls make this team useless. However Ludicolo can toxic stall them.
