Every time I try to do a Random Matchup in the Global Terminal it won't let me battle. It lets me in whenever I try, but before it actually gives me a chance to battle a random person it then tells me: 'There was a problem with your Pokémon, and they could not participate'. Each stat in my all of my Pokémon's EVs are no higher than 255, and none of them have the same item. They were made in an app called Pokébuilder. Here is my Black Version 2 team:

Dragonite F

Ability: Multiscale

Nature: Adamant

- Dragon Claw

- Extreemspeed

- Earthquake

- Fire Punch

Cloyster M

Ability: Skill Link

Nature: Impish

- Shell Smash

- Icicle Spear

- Rock Blast

- Razor Shell

Terrakion

Ability: Justified

Nature: Adamant

- Close Combat

- Stone Edge

- X-Scissor

- Swords Dance

Latios M

Ability: Levitate

Nature: Timid

- Draco Meteor

- Psychic

- Thunderbolt

- Surf

Spiritomb M

Ability: Pressure

Nature: Calm

- Dark Pulse

- Hypnosis

- Toxic

- Pain Split

Blissey F

Ability: Natural Cure

Nature: Calm

- Ice Beam

- Wish

- Toxic

- Heal Bell

I decided not to give them items and try it again, but it still didn't work.

None of them are shiny or have Pokérus. If anyone could find a website or a page with all the requirements, that would help.
