Gen 6 Double Battle Team Help

[BJAN456]

I have spent a lot of time breeding and EV-training some Pokemon, but I cant seem to get them to work in double battles. This is my first attempt at competitive battling, and I think I need some serious help.

Here's what I have so far:

Jolly Mamoswine w/ Thick Fat
Item: Focus Sash
Earthquake
Ice Shard
Icicle Crash
Stealth Rock (hasn't been particularly useful except against Talonflame/Charizard)
252 Atk / 252 Spe

Adamant Scizor w/ Technician
Item: Scizorite
X-Scissor
Bullet Punch
Swords Dance
Roost
252 Hp / 40 Atk / 216 SpD

Modest Dragonite w/ Multiscale
Item: Lum Berry
Draco Meteor
Fire Blast
Thunder Wave
Roost
252 HP / 252 SpA

Impish Gliscor w/ Poison Heal
Item: Toxic Orb (duh)
Toxic
Protect
Substitute
Rock Slide
244 HP / 40 Def / 224 Spe

Brave Aegislash w/ Stance Change
Item: Sitrus Berry
Sacred Sword
King's Shield
Shadow Sneak
Iron Head
252 HP / 252Atk

Calm Rotom w/ Levitate (Mr. Clean)
Item: Chesto Berry
Volt Switch
Hydro Pump
Will-o-wisp
Rest
228 HP / 28 SpA / 252 SpD

Adamant Azumarill w/ Huge Power
Item: Choice Band
Aqua Jet
Superpower
Play Rough
Waterfall
252 HP / 252 Atk

So I know they are all pretty standard, but how can I use some of them, add new Pokemon, and make a decent team? I also started building a Malamar set that may look like this:

Adamant w/ Contrary
Item: ?
Superpower
Psycho Cut
Topsy Turvy (For Dragonite's Draco Meteors)
?
EVs:?

Please contribute some knowledge, cause I could really use it.

I also use Malamar on most of my double battle teams. It is actually surprising useful, especially for Topsy-Turvy teams combos and spamming Superpower, although it is a bit slow and frail. I use a Sitrus Berry. You could also use Lum Berry or Leftovers. Night Slash should be used in the last moveslot. EVs are 252 Hp / 252 Atk. Be careful of special attackers and U-Turns. Anything else?
