This is a team that I made for a tourney with some friends. I'm a little rusty battling in doubles format, so I'd like more opinions on my team before I use it.
Politoad (F) @ Wacan Berry
EVs: 252 Hp/252 Sp. Def/4 Def
Politoad's main job is to set up rain, and stay in for as long as possible. Surf hits both opponents, along with healing one teammate. Ice Beam is for anything that resists Surf. Toxic (even though it probably won't be used much) and Protect can stall while causing damage, either through Poison or another Pokemon attacking.
Toxicroak (M) @ Muscle Band
Ability: Dry Skin
EVs: 4 Hp/252 Attk/252 Spd
Toxicroak is one of my physical attackers. Bulk Up is to boost attack, while raising defense to stay in longer. Sucker Punch is to get a decent hit on Latios, or any other annoying attacker. Drain Punch has good power, along with giving Hp back. Rock Slide is just to hit both opponents.
Normally, I would give it Black Sludge, but in this tourney, you can only use one of any item. It is already being used by another Pokemon.
Amoongus (M) @ Black Sludge
EVs: 252 Hp/128 Def/128 Sp. Def
-Hidden Power (Ice)
Possibly my biggest support/wall. I don't think I need to explain Spore, or even Giga Drain. Rage Powder helps me with setting up Toxicroak or Kingdra. HP Ice gives me something to hit Hydreigon or Latios with.
Gastrodon (M) @ Leftovers
Ability: Storm Drain
EVs: 252 Hp/124 Def/8 Sp. Attk/124 Sp. Def
Lots of people suggested Gastrodon over Ludicolo, so here it is. Muddy Water hits both Pokemon well, factoring in STAB and the rain boost. Earth Power, another good STAB attack. Toxic most likely won't be used a lot, but I can use it whenever I can. Recover is another way of healing than waiting for Leftovers. Hopefully, having this over Ludi, I can get some Sp. Attack boosts from another Pokemon's Surf, then pound the opponent with boosted attacks.
Kingdra (M) @ Lum Berry
Ability: Swift Swim
EVs: 168 Hp/164 Attk/4 Sp. Def/172 Spd
As far as I know of, SS + Drizzle is legal. If I hear otherwise, the ability will probably be changed to Sniper. With Kingdra, I wanted a Pokemon that could sweep, but didn't die after one hit. If I pair Kingdra with Amoongus, Amoongus can Rage Powder, aiming all attacks at it, while Kingdra can hide behind Substitute and set up. After Amoongus is gone, or Kingdra is fully set up, start attacking
Latios @ Choice Scarf
EVs: 4 Hp/252 Sp. Attk/ 252 Spd
I accidentally put Hardy nature (no boosts) instead of Modest when I first made this... I was wondering why his Special Attack was so low...
Latios is my only special attacker. I don't like the fact of having a choiced anything in doubles, but I didn't know what else to do. I guess Life Orb is a possibility. Draco Meteor for epic damage, surf to hurt both opponents (with good power from the rain), Thunder for 100% accuracy damage, and Psyshock for everything else. That's about it.
Please give me any thoughts/comments you have about this team!
