It's better if you just typed out the team, IMO, rather than using an attachment, since it may be painful clicking in and out of the pic as other people rate.
Life Orb is counterproductive with Dragonite's Multiscale, since one round of LO recoil if Dragonite attacks first at full health will render Multiscale useless. Also, consider this:
-Dragon Dance
-Dragon Claw/Outrage
-Thunder Punch/Fire Punch
-Earthquake/Roost
Nature: Adamant/Jolly
EVs: 252 Atk/4 SDef/252 Spe
Item: Leftovers/Lum Berry/Weakness Policy
Ability: Multiscale
It's not worth using two offensive moves on Blissey either. Its Special Attack isn't strong enough to make use of two high-powered offensive moves:
-Aromatherapy
-Seismic Toss/Flamethrower
-Softboiled
-Toxic
Nature: Calm
EVs: 4 HP/252 Def/252 SDef
Item: Leftovers
Ability: Natural Cure
All of Gardevoir's moves are 100% accurate, so there's no reason for it to use Wide Lens. Speaking of Wide Lens, it's not worth using:
-Calm Mind
-Moonblast
-Focus Blast
-Shadow Ball/Thunderbolt
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Life Orb
Ability: Trace
or
-Wish
-Protect
-Will-o-Wisp
-Moonblast/Psychic
Nature: Calm
EVs: 252 HP/4 Def/252 SDef
Item: Leftovers
Ability: Trace
LO + 4 attacks Scizor is terrible. Not only is Scizor slow, it wears itself down more easily with Life Orb, hazard and attack damage. Choice Band is the superior item and the only time for it to use Life Orb is for offensive trapping, Swords Dance and/or when it's using Roost:
-U-turn
-Bullet Punch
-Brick Break
-Pursuit/Quick Attack
Nature: Adamant
EVs: 248 HP/252 Atk/8 SDef
Item: Choice Band
Ability: Technician
or
-Swords Dance
-Bullet Punch
-X-Scissor
-Brick Break
Nature: Adamant
EVs: 252 Atk/4 SDef/252 Spe
Item: Life Orb
Ability: Technician
or
-U-turn
-Bullet Punch/Iron Head
-Brick Break
-Pursuit
Nature: Jolly
EVs: 252 Atk/4 SDef/252 Spe
Item: Choice Scarf
Ability: Technician
or
-U-turn
-Bullet Punch
-Pursuit
-Roost/Brick Break
Nature: Adamant
EVs: 248 HP/112 Atk/148 SDef
Item: Life Orb/Assault Vest
Ability: Technician
Gengar's Mega Stone is the Gengarite. Don't forget that. While Dazzling Gleam provides coverage against Dragons, Darks and Fightings, it may not be worth using until Lati@s and Terrakion are available:
-Shadow Ball
-Sludge Bomb
-Focus Blast
-Thunderbolt/Hidden Power (Fire)/Protect
Nature: Timid
EVs: 4 Def/252 SAtk/252 Spe
Item: Gengarite
I have issues with Aegislash's EV spread. Splitting the last half of its EVs into its defenses is a terrible idea and it squanders its overall bulk. The last half should go into its HP with the remaining 4 in either defensive stat or Speed. Leftovers is still the superior item, since Shell Bell is inferior to Lefties.
