Gen VI OU Team: Mega Altaria, suicidal Jirachi, and more!

Question

So I had this weird idea to create a team with two focuses: Azumaril and Mega Altaria. This is a very odd team, and I've never tested it, so it might just fail spectacularly, but any suggestions and advice would be appreciated.

VOLCARONA w/ Charcoal
Timid Nature (+Speed, -Attack)
Ability: Flame Body
-Quiver Dance
-Fire Blast
-Bug Buzz
-Giga Drain
EV Spread: 252 Special Attack, 252 Speed, 4 Special Defense

AZUMARIL w/ Life Orb
Adamant Nature (+Attack, -Special Attack)
Ability: Huge Power
-Play Rough
-Aqua Jet
-Belly Drum
-Superpower
EV Spread: 252 Attack, 126 Defense, 126 Special Defense, 4 Speed

JIRACHI w/ Light Clay
Impish Nature (+Defense, -Special Attack)
Ability: Serene Grace
-Light Screen
-Toxic
-Wish
-Reflect
EV Spread: 252 Defense, 252 Special Defense, 4 Speed

ALTARIA w/ Altarianite
Adamant Nature (+Attack, -Special Attack)
Ability: Pixilate (Natural Cure before Mega-Evolve)
-Dragon Dance
-Return
-Earthquake
-Roost
EV Spread: 252 Attack, 252 Speed, 4 Special Defense

ROTOM-WASH w/ Leftovers
Timid Nature (+Speed, -Attack)
Ability: Levitate
-Thunderbolt
-Hydro Pump
-Will-O-Wisp
-Pain Split
EV Spread: 252 Special Attack, 252 Speed, 4 HP

KYUREM-BLACK w/ Draco Plate
Naughty Nature (+Attack, -Special Defense)
Ability: Teravolt
-Dragon Claw
-Outrage
-Fusion Bolt
-Blizzard
EV Spread: 252 Attack, 248 HP, 8 Special Attack

The trick is this: get Jirachi out to put up Dual Screens, make a Wish, and switch with Azumaril. First turn, use Belly Drum, pray you don't get KO'ed, and have your health restored. Full HP, max Attack, Life Orb, Huge Power Azumaril with Dual Screens should be absolutely fearsome. Your screens will fade, though, and Life Orb will take its toll, and Azumaril will faint. The other Pokemon are to fill specific needs/coverage.

Any thoughts and ideas would be much appreciated. Thanks!

Wish doesn't work that way. It restores HP of the Pokémon on switch in when the turn ends. So u won't be able to belly drum and then have your HP restored. But u will be able to switch into a not super effective move and then have your HP restored, and then u can belly drum, but u will lose half your HP. And azumarill after that won't even last, specially with LO

Having 2 focuses is called a core and is the basis of every team. It's not exactly groundbreaking lol

Items like Charcoal and Draco Plates aren't usually very viable. They should be replaced by Life Orb or specific items like berries. Kyu-B should run Ice beam over Blizzard for the accuracy, since it'll only really be used against physical walls and pokemon weak to it, it doesn't need the extra power. Rotom should have a defensive nature and EV spread.

Volcarona: replace fire blast with fiery dance for accuracy.
