Possible water team

[Venks]

I've never really battled other players before and am greatly enjoying wifi. I'm just starting to learn EVs and am breeding trying to get the right natures.
I'm new, but yeah criticism is appreciated.
In case you can't tell I love water poke'mon.
Would this be good:

Poliwrath(Water Absorb)-Brave
Brick Break
Hydro Pump
Hypnosis
Rain Dance

Starmie(Natural Cure)-Modest
Surf
Psychic
Thunder
Light Screen

Lapras(Water Absorb)-Modest
Brine
Ice Beam
Rain Dance
Confuse Ray/Surf

Kingdra(Swift Swim)-Modest
Hydro Pump
Brine
Dragon Pulse
Dragon Dance

Quagsire(Water Absorb)- Brave
Muddy Water/Surf
Earthquake
Mud Sport
Rain Dance

Crawdaunt(Shell Armor)- Adamant
Night Slash
Crabhammer
Protect
Sword Dance

The idea was to use water poke'mon that supported each other, but yeah I'm new so any help would be great.
