I've always wanted to make a successful rain team, but I've never been able to, mostly because I can never figure synergy out. I'm good at using rain abusers, but they always tend to die because I can't find them the right support. Luckily, when I tried it in doubles, I had much better luck. The goal with this team is to get Kingdra or Ludicolo in, somebody else in, and surf to victory, hence the name "Hang 20". Bare with me as this is my first RMT.
Team
Politoed @ Water Gem
Trait: Drizzle
EVs: 252 HP / 200 Def / 56 SDef
Relaxed (+Def, -Spd)
-Surf
-Protect
-Icy Wind
-Helping Hand
How can you have a rain team with out the toed? EVs (like on all other pokemon on this team) are straight off Smogon. It's slow to under speed other weathers. I generally use Icy wind first to slow the other team so Jynx can outrun everything (especially after her sash broke and she has 1 HP). Surf is the next used move because it helps most of the team. Protect is just a filler. Helping hand is only used if Surf doesn't make sense and the the team is already slow, or, I want to be sure something dies. I didn't know what to do about the item so I just slapped a Gem on.
Jynx @ Focus Sash
Trait: Dry Skin
EVs: 4 Def / 252 SAtk / 252 SDef
Timid (+Spd, -Atk)
-Fake Out
-Lovely Kiss
-Ice Beam
-Protect
Jynx is a beast and deserves to be at the bottom of UU. On this doubles team, she is basically a Hitmontop. It's her responsibility to stop the most threatening opponent, while Politoed uses icy wind. After that, Jynx will either kill something, put a major threat to sleep, or protect if it seems like everybody will gang up on her. Jynx is only problem is her non existent defense, and that's where the Sash comes in.
Kingdra @ Life Orb
Trait: Swift Swim
EVs: 4 HP / 252 SAtk / 252 Spd
Modest (+SAtk, -Atk)
-Surf
-Dragon Pulse
-Ice Beam
-Protect
Kingdra is the other star of the team because of its super strong offence, able to outspeed everything, good defensive typing and surf. Dragon Pulse for 2nd stab but is usually reserved for other Kingdra, and Ice Beam has good coverage. Protect is usually just a filler. Life Orb to make him even more lethal.
Gastodon @ Rindo Berry
Trait: Storm Drain
EVs: 252 HP / 252 Def / SDef 4
Bold (+Def, -Atk)
-Surf
-Ice Beam
-Earth Power
-Recover
Gastrodon is a tank. It can take hits like nobody on this team can, and can dish them out after being hit by a couple of Surfs. Earth Power for stab and recover to keep him going. Rindo Berry is rarely (if ever) used so i'd like to switch it, I just don't know what to.
Ludicolo @ Life Orb
Trait: Swift Swim
EVs: 180 HP / 252 SAtk / 72 Spd
Modest (+SAtk, -Atk)
-Surf
-Giga Drain
-Ice Beam
-Fake Out
Ludicolo is Kingdra's happy/party animal twin. Basically plays the same as Kingdra with the exception of a little better coverage. Fake Out is just to buy a turn.
Toxicroak @ Black Sludge
Trait: Dry Skin
EVs: 252 HP / 252 Atk / 4 Spd
Adamant (+Atk, -SAtk)
-Fake Out
-Drain Punch
-Sucker Punch
-Protect
Toxicroak is Jynx's physical, more defensive, worse twin. This is the only spot I could see myself changing but I can't think of anything better that works with surf. Drain Punch does some damage but not much. Sucker Punch is really only used as a move before he dies. Toxicroak needs help hitting ghosts as everything besides Gengar (which isn't a threat) doesn't use attacks very much. Toxicroak also hates Gastrodon, and the only thing my team has against that is Ludicolo. Toxicroak does live forever seeing as he gets almost half of his health back each turn.
This team is super simple, as already stated. Set up rain, have Jynx kill trick roomers or any other major threat, let a swift swimmer and something else in and destroy everything with surf. Surf is great for my team as it only deals not very effective damage to the team members it doesn't help. This team is ridiculously easy to use as everybody has a partner that does the same thing it does and all I have to do is send in something that isn't weak against the opponent (Send in Kingdra to fight Scizor, instead of Ludicolo). Toxicroak is the only one who doesn't fully pull his weight and Politoed needs a new item so please help with that. Any other suggestions are greatly appreciated as well.
