[RATE MY TEAM] VGC 2015 Rain Team.

[Bad Guy]

I have been trying to build a doubles Rain Dance team. I'm looking for improvements, and a sixth member. I'm not sure if I should have a Pokemon with Stealth Rock, just to stop Talonflame and Mega Charizard.

Mega Swampert @Swampertite
Ability: Torrent -> Swift Swim
EVs: 108 HP/252 Attack/148 Speed
Nature: Lonely
Moves:
- Waterfall
- Ice Punch
- Earthquake
- Protect
Mega Swampert is my main Pokemon, it will be one of my leading Pokemon. Swampert needs the rain. Ice Punch is there to take out Landorus.

Ludicolo @Assault Vest
Ability: Swift Swim
EVs: 252 HP/84 Defense/148 Special Attack/4 Special Defense/20 Speed
Nature: Modest
Moves:
- Giga Drain
- Ice Beam
- Scald
- Fake Out
Ludicolo is here to take bulky water Pokemon, who may get in the way of Swampert. Ludicolo is nice with Fake Out.

Politoed @Damp Rock
Ability: Drizzle
EVs: 252 HP/112 Defense/20 Special Attack/112 Special Defense/12 Speed
Nature: Modest
Moves:
- Scald
- Ice Beam
- Encore
- Protect
Politoed is used to get the rain out there. The Damp Rock is helpful, since it increases the duration of Drizzle.

Noivern @Leftovers
Ability: Infiltrator
EVs: 4 HP/252 Special Attack/252 Speed
Nature: Mild
Moves:
- Draco Meteor
- Tailwind
- Roost
- Hurricane
Tailwind is useful if I can't set up the rain. Draco Meteor will also help against Mega Salamence, and Hurricane has a 30% of confusion.

Toxicroak @Black Sludge
Ability: Dry Skin
EVs: 76 HP/252 Attack/180 Speed
Nature: Adamant
Moves:
- Protect
- Drain Punch
- Poison Jab
- Fake Out
Toxicroak is good to take out fairy types. Dry Skin is helpful since this a full rain team.
