I decided to make a weather team, so I went with rain. I haven't done any training on any of these guys yet, so there is plenty of room to change or replace these Pokemon. Any help is appreciated. Here is what I have so far:
EVs: HP-252 / Def-252 / SDef-4
The obvious weather lead. This is the bulky Politoed, so that I don't lose my weather inducer.
EVs: HP-252 / SAtk-108 / SDef-148
Special Tank Dragonite. Hurricane is STAB and 100% in rain. Thunder is 100% in rain also. Roost to increase its longevity. Dragon Tail to phase any counters.
Toxicroak@ Life Orb
Ability: Dry Skin
EVs: HP-4 / Atk-252 / Spe-252
Physical Attacking Toxicroak. Utilizes Dry Skin to recover Life Orb recoil.
Volcarona@ Life Orb
Ability: Flame Body
EVs: SAtk-252 / SDef-4 / Spe-252
Though somewhat out of place in the rain, This Volcarona is here to counter any Grass/Steel types that give me trouble. Quiver Dance to set up, Bug Buzz is STAB, Hurricane for 100% Flying, and Fiery Dance to get the Special Attack boost.
Ferrothorn@ Shed Shell/Leftys
Ability: Iron Barbs
(+SDef, -SpA) Nature
EVs: HP-252 / Def-88 / SDef-168
-Leech Seed/Power Whip
This is a pretty standard Ferrothorn. Set up hazards and cripples with Thunder Wave. Not sure whether I should use Leech Seed or Power Whip.
Starmie@ Damp Rock
Ability: Natural Cure
EVs: Def-4 / SAtk-252 / Spe-252
Starmie is my Rapid Spinner. Surf is STAB, Thunder for obvious reasons. I have the Rain Dance/Damp Rock combo here to counter other weather starters and/or to set up rain if Politoed can't for some reason.
