um....well heard of swampert/quaqsire/whiscash? may wanna invest in some Hidden Power grass
Lanturn @ life orb/damp rock
Timid/Modest
Volt absorb
252 sp. atk/ 252 spe/ 6 hp
thunderbolt/thunder
hidden power grass
ice beam
rain dance/ charge beam
first and laast slots are important. thunder ONLY if you want rain dance support,which can be good if you have a swift swimmer. charge beam raises your sp. atk,thus making t-bolt stronger. HP grass so the before mentioned ugly fish things dont earthquake you to death. ice beam is mostly filler, but can 3HKO(at the most) Gyarados and kingdra.
