some noteable pokes:
Lapras (very bulky & tons of potential)
Politoad (suprisingly bulky and strong)
Empoleon (a million resistances....)
Poliwrath (great physical choice but not as hot as...)
FERALIGATR (best physical water guy plus it can get dd)
Mantine (ridicously high sp. d- if you keep it away from electrics its an amazing wall)
Gorybyss (great sp. a & speed- 2nd highest water sp. a) 2nd highest water type Special Attacker
Omnastar (Keep away from grass and he is strong and physically bulky) highest water type Special Attacker
Quagsire (stockpile + recover: expect to this poke rise to popularity as those are two new epic moves)
slowKing/SlowBro (calm mind+slack off= very dangerous)
Lanturn (volt absorb, stockpile, and aqua Ring + 1038593829857hp make it a decent wall also hhas great type coverage)
i didnt mention: gyardos, milotic, vaporeon or swampert because everyone knows about those. These will give you some options
