Pokemon White: Nimbasa

Sick again today, so still playing all day...
I completed Nimbasa gym about an hour ago, but forgot to write down stuff immediately. So, here I am on Route 5, heading to Driftveil City!
My Pokemon...

Tranquill: Level 24, (Gust, Roost, Air Cutter, Quick Attack), (43 atk, 41 def, 31 spatk, 26 spdef, 41 spd, 63 HP), ability is Big Pecks, holding a Smoke Ball
Solosis: Level 24, (Snatch, Hidden Power, Light Screen, Charm), (25 atk, 30 def, 57 spatk, 35 spdef, 16 spd, 59 HP), ability is Magic Guard, holding an Exp. Share
Herdier: Level 28, (Crunch, Take Down, Strength, Bite), (51 atk, 45 def, 32 spatk, 47 spdef, 46 spd, 81 HP), ability is Sand Rush, holding BlackGlasses
Sandile: Level 23, (Dig, Cut, Sand Tomb, Assurance), (44 atk, 22 def, 25 spatk, 25 spdef, 37 spd, 57 HP), ability is Moxie, holding Soft Sand
Simipour: Level 23, (Scald, Bite, Dig, Cut), (50 atk, 45 def, 50 spatk, 35 spdef, 58 spd, 73 HP), ability is Gluttony, holding Mystic Water
Swadloon: Level 25, (Tackle, Grass Knot, Bug Bite, Razor Leaf), (38 atk, 59 def, 36 spatk, 49 spdef, 30 spd, 65 HP), ability is Chlorophyll, holding a Miracle Seed

For the gym itself, I actually had a Yamask instead of a Solosis, but I switched to Solosis a few minutes ago. I'm working on getting a Minccino, which I actually would like to switch Herdier with. I'll probably keep them both around for a while, since I'll be switching Tranquill and Simipour out for a Ducklett in just a little while here.
I'm still waiting for my Swadloon to evolve into a Leavanny. Swadloon, why you hate me? ;<
I'm not entirely fond of Sandile either. I'm formulating my entire team at the moment. I'm thinking Cinccino, Reuniclus, Swanna, Eelektross, Leavanny, Hydreigon. Until I can actually get a Hydreigon though, I'll probably use a Golurk. Once Golurk can fly, I may consider switching Swanna out and using a Jellicent. I may not even use a Hydreigon at all! Not sure yet...Still solidifying my idea...
