New Sort of Rain Team

This is my first time really making a team by myself.
I am aiming to make a good rain team that can utilize swift swim while not using drizzle.
Here goes:

Hidden Power (Ice)

Kabutops - Swift Swim
Adamant, Leftovers
252 Att, 252 Hp, 4 Spe

Aqua Jet
Waterfall
Stone Edge
Swords Dance

Volcarona - Flame Body
Modest, Lum Berry
252 Sp.A, 252 Sp, 4 Hp
Hurricane
Quiver Dance
Bug Buzz
Hidden Power (Water)

Ludicolo - Swift Swim
Modest, Damp Rock
252 Sp.A, 252 Hp, 4 Hp

Ice Beam

Lapras - Hydration

252 Att, 252 Sp, 4 Hp
Rest

Outrage
Waterfall


Gastrodon - Storm Drain

252 Sp. A, 252 Sp, 4 Hp
Earth Power

Surf

Tell me what you guys think!
It's still a work in progress, so update may happen.

Since Brongxong has a special attack on it with a Impish nature it would be easier to replace Psyshock with Earthquake or give it a Relaxed nature with 0 speed IVs and then give it Gyro Ball.

For Ludicolo replace Focus Blast with the STAB Surf since it gets the rain boost and STAB boost and has a lot more power and accuracy then a Focus Blast after this. You can also give it a Life Orb and Giga Drain to make it even more destructive.

Gastrodon is already slow as mud,and any more speed isnt nessecary,so maximize its HP instead so it can act as more of a tank. Give Volcarona HP Rock instead of HP Water so it can hit Fire types who try to wall it as well as some Flying types like Dragonite and Tornadus-T.

And finally for Kabutops give it 252 ATK / 252 SPD so it can outspeed +1 Dragonite and Choice Scarf Genesect.
