NEW TEAM LINEUP, go find my latest post on this thread.
Okay, so this is the reason I signed up for Smogon: to get advice on how to create teams.
Specifically, this Rain team which I'm setting up in Black/White 2, using Smogon's strategy database as my reference. I'd like some pointers on how to improve it or fix glaring flaws that I may have missed.
TEAM BUILDING TIIIIIIIME
I hate weather changes, so which weather do I have the least trouble with and I can take advantage of the most? Rain.
BAM! Politoed.
I also hate hazards, but only on my side. Also, Pokemon slots are pretty valuable.
Shove off Ferrothorn, you don't have Rapid Spin.
Now what kind of Pokemon can take hits well and really thrives in rain...? Well, Kingdra has Swift Swim but people seem to think Drizzle with Swift Swim is HAX, so how about...
Meh. Blissey wouldn't have good synergy anyway.
Okay, now I need a guy that punches things to make them fall down.
No-brainer.
But wait! Scizor has U-turn! That means I can have like half a VoltTurn team in there!
Presto!
Whoops, looks like I made half my team the Water-type. So I'll need a Pokemon that's not Water, yet can still take advantage of the rain.
Oh Dragonite, I've always believed in you since 1st Gen.
And there we go! I'm INSANE!

Politoed @ Choice Specs
Trait: Drizzle
EVs: 252 HP / 6 Def / 252 SpA
- Hydro Pump
- Ice Beam
- Hidden Power Grass
-
This is the bread-and-butter Politoed of OU. Politoed's main use is to set up rain so that the rest of the team can function, and until I'm sure that there are no more weather changers on the opponent's side, I'll need to keep Politoed as healthy as possible, so it usually won't be seeing many battles unless it's up against a Pokemon I know it can win against. Once all threats to the weather are gone, it can act as another special sweeper, with its STAB rain-powered Hydro Pump being able to murder even water-resistant Pokemon, though it's non-100% accuracy deters me from depending on it.
On the recommendation of labarith, I made it Quiet and got rid of Focus Blast for something more reliable: Perish Song. This will force switches and ruin opponents who rely on set-ups to be effective.

Forretress @ Shed Shell
Trait: Sturdy
IVs: 0 Spe
EVs: 252 HP / 6 Def / 252 SpD
Relaxed Nature
- Stealth Rock
- Rapid Spin
- Volt Switch
- Gyro Ball
Forretress has three jobs: set up Stealth Rock, spin away hazards, and take hits. The longer Forretress stays on the field, the more danger it is in, so it needs to switch out as quickly as possible after it has done its job. Shed Shell allows it to escape from Magnet Pull Magnezone before it takes any damage, while Volt Switch allows it to retreat after taking a hit, allowing me to safely switch in my other Pokemon. There's also Gyro Ball, which is there so that Forretress won't be completely useless on its own, but it's not going to be used that often.

Vaporeon @ Leftovers
Trait: Hydration
EVs: 248 HP / 252 Def / 10
Bold Nature
- Scald
- Rest
- Wish
-
This tank is responsible for keeping the rest of my team healthy. To be honest, I was torn between this one and Umbreon, what with Umbreon being able to clear status with Heal Bell at the cost of Wish recovery and any sort of viable offensive, but I figured I needed a healer/tank that can provide adequate firepower and really take advantage of the rain that this team revolves around. Rest with rain up ensures that anything less that an OHKO will do anything to it.
Apparently Vaporeon can also have Heal Bell. So there we go.

Scizor @ Choice Band
Trait: Technician
EVs: 248 HP / 252 Atk / 10 Spe
Adamant Nature
- U-turn
- Bullet Punch
- Pursuit
- Superpower
Everyone's favorite U-turning mass murderer, Choice Band Scizor is my main physical damage dealer and VoltTurn partner for Rotom-W. The one thing I worry about is that Scizor shares the same Bug/Steel typing with Forretress, which means that Fire will deal major damage to both of them despite the rain, but as long as key team members like Politoed and Vaporeon can support them, they'll be able to do their job.

Rotom-W @
Trait: Levitate
EVs: 248 HP / 28 SpA / 234 SpD
Calm Nature
- Volt Switch
-
-
- Pain Split
Rotom-W can take the hits that Scizor can't
Nobody likes anything with less than 100% accuracy, so I dropped Hydro Pump and replaced it with Thunder. Hidden Power Ice is to cover Thunder's ineffectiveness against ground.

Dragonite @ Lum Berry
Trait: Multiscale
EVs: 252 HP /
- Hurricane
- Thunder
-
- Roost
I'm using Dragonite because I needed another powerhouse who can take advantage of the rain. STAB Hurricane hurts, plain and simple. Thunder is for coverage,
I took labarith's advice and swapped out Waterfall for Substitute, giving Dragonite more survivability and allowing it to abuse Multiscale even more. Since there are no more physical attacks on its moveset, I changed its nature to Modest and adjusted the EVs for maximum offensive power and HP.
This is my first time doing this sort of thing, so I'm not sure if I'm even posting this right.
