So I see all these people using rain teams and I thought I would make one too. Although I did not use the traditional Politoed lead since it is banned to have Drizzle and Swift Swim so here we go.
Azelf
@Damp Rock
Nature: Jolly (+Speed -Attack)
Ability: Levitate
EVs: 252 Hp / 4 Def / 252 Spe
-Rain Dance
-U-Turn
-Taunt
-Stealth Rock
Azelf is an awesome lead with its incredible speed allows to out speed leads such as Forretress. Although Espeon can be a pain not allowing for me to use Stealth Rock and/or Taunt. U-Turn can put a large dent in it though, but I'm not a fan of U-Turn, it can allow me to switch into a sweeper but I'd rather not get damage on my sweepers. It also can get me a second Rain Dance in when/if the first one ends.
Kingdra
@Life Orb
Nature: Modest (+SpAttack -Attack)
Ability: Swift Swim
EVs: 88 Hp / 252 SpAtk / 168 Spe
-Draco Meteor
-Dragon Pulse
-Surf
-Rain Dance
Swift Swim allows Kingdra to out speed almost anything and with its large STAB Surf, plus Rain (also much for reliable that Hydro Pump), it can be destructive even to a grass type pokemon such as Venasaur. Dragon Pulse gives a steady coverage move over Dragonite and Latios/Latias and Draco Meteor for a big bang on Roserade.
Sharpedo
@Life Orb
Nature: Adamant
Ability: Speed Boost
EVs: 252 Atk / 4 Def / 252 Spe
-Waterfall
-Crunch
-Earthquake
-Protect
Sharpedo is a beast, even without Swift Swim it can use Protect ONCE it can over speed every OU Pokemon (according to Smogon). With rain Waterfall can OHKO Tyranitar, Infernape, Gliscor and many others. Crunch being a swell STAB for Espeon, Alakasam, and Latios. Earthquake covers that large resistance to Steel Types which can be a large pain for this team. I had Ludicolo before Sharpedo but was unable to get Drain Punch on him, so Sharpedo is a very strong and fast replacement.
Tornadus
@Life Orb
Nature: Timid (+Speed -Attack)
Ability: Prankster
EVs: 4 Hp / 252 SpAtk / 252 Spe
-Hurricane
-Focus Blast
-Rain Dance
-Taunt
Tornadus is a powerhouse! Rain Dance is just another way to set up rain incase Kingdra faints. Hurricane is extremely crazy in the rain, more accuracy, more power, and then the chance to confuse the opponent. Which can help with Steel Types, along with Focus Blast. More coverage for Steel types and Tyranitar as well. Taunt is for the annoying Ferrothorn (which is my least favorite competitive pokemon).
Parasect
@Leftovers
Nature: Careful (+SpDefense -SpAttack
Ability: Dry Skin
EVs: 252 Hp / 172 Def / 84 SpDef
-Spore
-Leech Seed
-Aromatherapy
-X-Scizzor
This mushroom thing is one of my favorite competitive pokemon ever! Spore always puts pokemon to sleep thanks to that 100 accuracy. Leech Seed allows Parasect to receive even more health besides Leftovers and Dry Skin (which allows it to be resistant to water) plus allows it to switch into other pokemon for some health while the foe is asleep. Blissey allows for some extreme recovery. Lastly Aromatherapy for those who have been paralyzed by Ferrothorn's Thunder Wave or poisoned by Umbreon .
Porygon2
@Eviolite
Nature: Quiet
Ability: Download
EVs: 252 Hp / 4 Def / 252 SpAtk
-Tri Attack
-Recover
-Ice Beam
-Thunder
This thing is tough to knock out, and even when its health gets low RECOVER. And with rain going in Thunder gets full accuracy even doing lots of damage to Metagross. Tri Attack gets STAB then a chance to burn, freeze, or paralyze. It can get another freeze from Ice Beam and another paralysis from Thunder. This thing is packed with defenses and deserves the rightful named of 'Duck Tank'
