Pokemon Black Version 2

I've been building a triple team which has done okay I guess in PWT, but haven' tried it online.

My pokemon:

Sawsbuck:
Adamant
Horn Leech
High Jump Kick
Agility

I'm pretty much trying to build the team around him. He is a beast, unless he gets by a fighting move :(

Leafeon:
Impish
Leaf blade
Synthesis
Heal Bell
Sunny Day

When I was breeding him I think I was going for a sun team with Sawsbucks Chlorophyll, but I mostly spam leaf blade and synthesis with him. Can take hits though :p I don't mind switching him out for something to give me more coverage

Mienshao:

Impish
Fake out
U-Turn
Drain Punch
Stone Edge

He is decent, but seems to be getting outsped a lot for some reason and if he gets hit he pretty much is done for.

Snorlax

Adamant
Fire punch
Seed bomb
Body Slam
Crunch

Straight up attacker that can take most hits, but I like him so far.

Lapras

Calm
Whirlpool
Perish song
Ice Beam
Rest

Yea.....was supposed to be a perish trapper for singles and I've found it doesn't work well for triples lol

My sixth pokemon was a Jolteon I went through the game with.

So as it stands Snorlax and Sawbuck are solid, Mienshao has been underwhelming, but maybe I'm not doing it right lol. And Leafeon can stay or go doesn't matter much to me.

I was thinking of adding Litwick to help with psychics and fighting types as well as grass and steel. Growlithe was another pokemon I was considering.

So any suggestions?
