Here is my New Rain team after some changements.
Electrode : The Leader

Nature : Jolly
Ability : Static
252 Attack/ 4 HP / 252 Speed
Item: Damp Rock
Moveset: Rain Dance
Explosion
Taunt
Mirror Coat
I must admit, Electron is a way better Leader for a Rain Team than Crobat. With its very high speed, Electrode outspeed nearly everything. I usually start off with Taunt. This prevents the foe to use SR, spikes or walls. After Taunt, I use Rain Dance, which lasts longer with Damp Rock equipped. Once Rain Dance done, I choose between Explosion and switch. Mirror Coat can surprise many foes. Giving Thunder instead of Mirror Coat could be a good idea. However, I should invest EV in Special Attack instead of Attack, which would lower the damage done by Explosion.
Ludicolo: Sword Dancer

Nature : Adamant
Ability : Swift Swim
252 Atk/252 Speed/ 4 HP
Item: Life Orb
Moveset: Sword Dance
Seed Bomb
Ice Punch
Waterfall
This guy, once under rain and gotten Sword dance, can destroy everything. I mainly use him only under rain in the early game. Ice Punch is to kill Dragon trying to Outrage me. Waterfall is my main STAB attack which I use for neutral damage. If the foe is resistant to Water, I use Seed Bomb. A good example is Swampert. Life Orb and the Adamant Nature is to cause maximum damage. A Jolly Nature isn’t necessary because of Swift Swim. Because it is a Sword Dancer, he can’t obviously get a Choice item, that’s why I chose Life Orb.
Starmie: (After the Rain: The Rainbow)

Nature : Timid
Ability : Natural Cure
252 Special Attack /252 Speed/ 4 HP
Item: Life Orb
Moveset: Surf
Ice Beam
Thunderbolt
Psychic
I mainly use Starmie in the late-game, when there is no more Rain. With its still impressive speed, it can outspeed most of the non-scarf foes, allowing it to 2HKO pretty much everything. Surf is its main STAB attack. Psychic is here against Machamp or Water-resistant enemies. Most players don’t except Psychic on Starmie. Vaporeon sometimes switch out for a Ground-type, excepting a Thunderbolt and got it by a Psychic Attack. Ice Beam is obviously against Dragon-type and Finally, Thunderbolt allows me to hit hard Water-type, OHKOing Gyarados (obviously).
Kingdra: The Killer...

Nature : Modest
Ability : Swift Swim
252 Special Attack /252 Speed/ 4 HP
Item: Life Orb
Moveset: Surf
Dragon Pulse
HP Electric
Rain Dance
Once under the Rain, Kingdra is very hard to beat. With Life-orb, Modest Nature and 252 Special Attack, Kingdra does high damage to nearly everything. Surf is its main STAB attack as well as Dragon Pulse against other Dragons or Water-resistant Pokemons. The duo Electric-Water works very well against most foes.
For the fourth and last slot available, I was wondering if Rain Dance would be the best option or Signal Beam. With Life-Orb equipped, Kingdra doesn’t have many chances to survive to an attack while setting Rain. Signal Beam could help me against more foes.
Rotom-w : Re-Rainer

Nature : Modest
Ability : Levitate
252 Special Attack /4 Special Defence/ 252 Speed
Item: Damp Rock
Moveset: Rain Dance
Hydro Pump
Shadow Ball
Thunder
Mainly, its job is to cause the Rain once the one created by Electrode has finished. Then, using its high Special-Attack boosted by the Modest Nature and its EVs, kill as much Pokemon as he can. Thunder has 100% accuracy under Rain and is its main STAB attack. Hydro Pump is very useful against Ground-type which are unaffected by Electric moves. Shadow Ball is there to complete a wider range of attacks.
Kabutops: Sword Dancer

Nature : Adamant
Ability : Swift Swim
32 HP/ 252 Attack / 204 Speed
Item: Life Orb
Moveset: Waterfall
Stone Edge
Sword Dance
Brick Break
Under the Rain, even if he only has 204 EV in Speed and a Adamant Nature, Kabutops will outspeed all the non-scarf Pokemons. Life Orb, its nature and 252 Ev in Attack gives him a lot of power. Waterfall is its main STAB attack followed by Stone Edge that hits Flying-type mostly. After having placed a Sword Dance under the rain, Kabutops becomes very hard to stop. Brick Break helps a lot against Normal-type such as Smeargle and Blissey, as well against Tyranitar.
