My New Rain Team

I know I posted not long ago a team but the competitive batteling
had really impressed me and I began to like it.
But I'm not really good at making a team and I'm not sure that this
is a good team or not. That's why I need your help.Please rate my team.

Vaporeon is better off on dedicated Baton Pass teams, IMO.

I don't think White Herb is that useful unless it's for Shell Smash. A specially-based set is better than a mixed one:
-Hydro Pump
-Draco Meteor
-Surf/Ice Beam/Hidden Power (Fire)
-Dragon Pulse/Ice Beam/Hidden Power (Fire)
Nature: Modest
EVs: 24 HP/252 SAtk/232 Spe
Item: Choice Specs
Ability: Swift Swim

I'd rather have Jirachi be more of a general supporter than a backup rain setter because I have something else better that I can suggest over Vaporeon (more later):
-Iron Head
-Wish
-U-turn/Stealth Rock
-Stealth Rock/Thunder/Body Slam
Nature: Careful/Sassy
EVs: 252 HP/236 SDef/20 Spe
Item: Leftovers

Tornadus is a better rain setter because of Prankster and the fact that its Hurricane never misses in rain:
-Rain Dance
-Hurricane
-Superpower/Focus Blast
-U-turn/Taunt
Nature: Naive/Timid
EVs: 4 Atk/252 SAtk/252 Spe
Item: Damp Rock/Life Orb
Ability: Prankster
