Oh and they can only be the new ones except Victini, Zekrom, Reshiram, Keldo, Meloetta, or Genesect. Those 6 are not allowed.

EVs/items/natures would be nice, otherwise it's pretty difficult to rate teams by competitive standards.

Ok, I put all of that in it now. It's now the Pokemon, its item, nature, maxed EV stats, and moves.

I'm assuming this is a VGC team?

Ok, so I'm making a competitive Double Battle team for the World Championship series, and I need some help with it. I would like some input on people that actually know what they're talking about. Here's what I have:
Mienshao @ Fighting Gem/Focus Sash
Jolly; 4 HP/252 Atk/252 Spe
Rock Slide
Fake Out
Drain Punch
Wide Guard/Protect

You barely have time to use U-turn in VGCs since everything there happens quickly.

Hydreigon @ Chople Berry/Life Orb/White Herb
Modest/Timid, 4 HP/252 SATk/252 Spe
Dragon Pulse/Draco Meteor
Flamethrower/Focus Blast
Surf
Protect/Taunt

Normally, this Hydreigon would've used Dark Pulse, but since it's an egg move, Surf might be the option here.

Reuniclus @ Life Orb
Modest, Maxed Sp Attack/HP
Psychic
Safeguard
Shadow Ball
Focus Blast

Jellicent
-Scald/Energy Ball
-Water Spout
-Shadow Ball
-Ice Beam/Blizzard
Nature: Timid/Modest
EVs: 4 HP/252 SAtk/252 Spe
Item: Choice Scarf

Alomomola isn't that good, IMO.

Honestly, since VGC matches happen quickly, I'll add a couple of Tailwind users to boost your team's Speed:

Tornadus
-Acrobatics
-Tailwind
-Substitute/Protect
-Taunt
Nature: Jolly
EVs: 4 HP/252 Atk/252 Spe
Item: Flying Gem
Ability: Prankster

Whimsicott
-Tailwind
-Taunt/Giga Drain
-Encore/Giga Drain
-Protect
Nature: Timid
EVs: 252 HP/4 Def/252 Spe
Item: Focus Sash
Ability: Prankster

Mienshao @ Muscle Band

Attract attract is kind of wasted, try acrobatics or stat up moves for this..
Dig fine but stone edge is way more useful
Drain Punch
U-Turn

Hydreigon @ King's Rock
Sassy, Maxed Attack/Sp Attack
Outrage
Thunder Wave This is enhhg try calm mind or if u want, scary face or even tri attack (lv.1 ) taunt or toxic works too
Flamethrower
Earthquake

Reuniclus @ [COLOR=blue ! important][FONT=inherit ! important][COLOR=blue ! important][FONT=inherit ! important]Focus[/FONT][/FONT][/COLOR][/COLOR] Band
Rash, Maxed Sp Attack/HP
Psychic
Safeguard /for survival calm mind, but this is A OK too
Energy Ball
Focus Blast
Works well:)

Alomomola @ Leftovers
Jolly, Maxed HP/Speed
Attract / toxic, thunder wave ( works because ground won't be like," oh hi! Its a water type! Let's go and get it! It is faster than me! YAY" no, so u should be find
Heal Pulse
Water Pulse surf or scald works too, because when it burns it lowers attack and guranteed HP damage
Ice Beam

Cofagrigus @ Rocky Helmet
Sassy, Max Sp Def/ Def
Protect
Will-O-Wisp
Night Shade
Curse

Mandibuzz @ Scope Lens
Hasty, Max Speed/Sp Defense
Swagger Will SO back fire. U are asking for HEY! STONE EDGE ME!! Do taunt or torment, can shut a team down easily
Punishment
Toxic
Aerial Ace

If you have any advice, please let me know.
A quite good team.. Alommola is reallly weak, HP is great but no defenses means it won't do anything... Try a seisimitoad and have it learn an ice type move and then it might be better, but you go for it:) Nice JOB!
