So lets have some fun here and through some fun sun abusers in the rain eh? And a bit of water STAB is never a bad idea either. Lets get going!!!
Hax Poli(Politoed) @ Leftovers
252 HP/ 4 Def/ 252 SpD
Politoed is going bad style. He decides to come in and get the party going with a Substitute then has Toxic, Scald, and Ice Beam to continute his haxing. So Scald for STAB its unique chance to burn is amazing against pokemon such as Tyranitar, Breloom, Gyarados, Skarmory, and the like of them. Ice Beam gives some coverage. He is shut down by Forretress, Heatran, and Ferrothorn especially. But Toxic is grerat for most anything else.
King of the High Seas (Kingdra) @ Leftovers
40 HP/ 228 Atk/ 12 Def/ 228 Spe
Kingdra's gon gangsta. He just gets in the groove and moves with it. In or out of Rain he is a beast. Dragon Dance raises your speed making him making him even harder to take down. And he also gets a deadly attack boost at the same time. Waterfall is powerful STAB and boosted by rain to KO a lot of the metagame. Outrage hits like a beast and a +1 OHKOes a great deal of the OU/UU pokemon. Substitute is simple as a safeguard. Set it up and then he is almost unstoppable. He is absolutely BAWS with a substitute and DD in. And don't forget that a Sniper boosted crit. Outrage will OHKO anything it hits I believe.
Hidden Pokemon(Forretress) @ Shed Shell
252 HP/ 252 Def/ 4 SpD
Set up Tress. Nuff Said.
Hurricarona (Volcarona) @ Life Orb
252 SpA/ 4 SpD/ 252 Spe
Yes the origanal Hurrican set has returned! And in full glory. HE just crushed everything he encounders bar bulky Rock/Steel types. Quiver Dance makes him such a formidable sweeper, your opponent will be ripping their hair out at the sight of this. If rain was bad enough, this is worse. Hurricane runs like a hurrincane, it decimates the trailer park of your opponent. Bug Buzz hits most things hard after a +1. And Fiery Dance is great if your opponet has a surprise Sunny Day up their sleave. Whos surprised now!
SPDachi (Jirachi) @ Leftovers
252 HP/ 224 SpD/ 32 Spe
What status does your opponent really hate? The one that is most annoying. That status is called SPDachi. He is the SpD wall here to soak Thunders directed at Poli and the bug. Iron Head is still just as annoying as ever. Just watch your opponent gouge at their eyes as they try to stop you. Body Slam is for status and a bit of damage. Wish is for healing of the damage you soaked. And Fire Punch is just for those nasty fighting types who like to spam Close Combat. NOT! Mwhahahaa
Killnape (Infernape) @ Life Orb
252 Atk/ 4 Def/ 252 Spe
This is the teribble terror of this team. He is my user to screw over those that use Substitute. Close Combat is the usually spamming weaon of choice. Thunder Punch is to hit any curious water or flying types back to their mamas. And the added coverage is greatly appreciated. Flare Blitz can be useful if some one tricks you and throws some sun in. Dual Chop hits hard and also breaks subs pretty easily. Last, who suspects an Infernape on a rain team. He is completely unexpected.
