Double Battle, Tailwind Team (Still making it)

Dragonite-150 HP/252 Atk/102 Spd
Item: Yache Berry
Ability: Inner Focus
Nature: Adamant/Jolly
ExtremeSpeed
Dragon Claw
Thunder Punch
Protect
Dragonite is a good lead Pokemon who can prevent Fake Out with Inner Focus. Tailwind support will let Dragonite out speed everything except Ninjask. It's just a general attacker.

Metagross-252 HP/240 Atk/4 Def/12 Spd
Item: Occa Berry
Ability: Clear Body
Nature: Adamant
Bullet Punch
Meteor Mash
Earthquake
Protect
Metagross's great typing along with it's stats will let it stick around a while while dishing out some major damage. Then tailwind increases it's speed which allows it to out speed Pokemon like Garchomp or Salamence.

Lickilicky-252 HP/240 Atk/8 Def/8 SpDef
Item: Chople Berry
Ability: Cloud Nine
Nature: Careful/Impish/Adamant
Sunny Day
Return
Power Whip
Protect
Lickilicky is my major counter to weather. I don't see sun teams nearly as much as sand, or rain teams so I gave it sunny day in case they re-summon weather after cloud nine. Power Whip helps against water, and ground types. While return gives it a good STAB move.

Blaziken-4 HP/252 Atk/252 Spd
Item: Life Orb
Ability: Blaze
Nature: Adamant/Jolly
Hi Jump Kick
Flare Blitz
Brave Bird
Protect
Blaziken is my fire type. Allows major damage with STAB Flare Blitz, and Hi Jump Kick. Then Brave Bird as another super strong move.

Suicune-252 HP/252 SpAtk/4 SpDef
Item: Leftovers
Ability: Pressure
Nature: Bold/Timid/Modest/Calm
Ice Beam
Hydro Pump
Calm Mind
Protect
Suicune is my wall. Calm Mind allows it to increase it's special attacking, and special defense stats. While Ice Beam can take down those Garchomps' and Hydro Pump is for a good STAB move.

Whimsicott-252 Spd
Item: Focus Sash
Ability: Prankster
Nature: Timid/Jolly
Helping Hand
Tailwind
Endeavor
Protect
Whimsicott is my setter-upper of Tailwind. Low defenses allow Focus Sash to kick in with in combination of high speed allows Endeavor to lower bulky Pokemon like Cresselia to 1HP! Then Protect to do a little stallin.
