UU Rain Dance Team

I'm new to battling competitively so please tell me everything wrong with my team and what I should do to fix it. Anyway here's the team:

Electrode-Damp Rock
Ability:Soundproof Nature:Hasty
Rain Dance
Explosion
Taunt
Thunder
Evs:252 Atk/48 Spa/208 Spe
This is straight off of Smogon Electrode seems like the best lead to me personally due to his high speed and his taunt can stop spikes.

Kabutops-Life Orb
Ability:Swift Swim Nature:Adamant
Swords Dance
Aqua Tail
Stone Edge
Aqua Jet
Evs: 252 Atk/252 Spe/4 HP
Physical Sweeper. Aqua Jet for revenge killing.

Ludicolo-Life Orb
Ability:Swift Swim Nature:Modest
Surf
Energy Ball
Ice Beam
Rain Dance
Evs: 252 SpA/252 Spe/4 HP
Special sweeper, also used to take out water types in the rain. Can set up rain if it goes away too.

Chansey-Leftovers
Ability:Natural Cure Nature:Calm
Wish
Protect
Seismic Toss
Thunder Wave
Evs: 252 SpD/252 HP/ 4 Def
Wish for healing my sweepers, I'll switch in when they have a special sweeper T wave to slow them down, or wish to heal my sweepers.

Cloyster-Leftovers
Ability:Shell Armor Nature:Bold
Rain Dance
Protect
Rapid Spin
Explosion
Evs: 252 HP/252 Def/4 Atk
Not really sure about Cloyster... seems pretty pointless other than for keeping up rain and getting rid of spikes.

Leafeon-Leftovers
Ability:Leaf Guard Nature: Jolly
Baton Pass
Swords Dance
Synthesis
Leaf Blade
Evs: 252 Spe/252 Def/4 HP
I know this seems weird in a Rain Dance team but Leafeon is great for baton passing Swords Dance to Kabutops.

This is my first team I've made, I haven't used it yet either just trying to throw out some ideas and get some suggestions back.

Thanks I really wasn't sure on the last 3 pokemon at all but I had to post a full team. I didn't even think of the Toxicroak weakness either.

get a politoed with drizzle from the dream world
that would help a lot
