Bullet Seed should only be used if you're deathly afraid of Hippowdon, Azumarill and Wash Rotom. Earthquake is generally preferred over it so that Mega Heracross isn't walled by Aegislash. Also, Close Combat > Arm Thrust. If you do use Arm Thrust, not only does Mega Heracross lose out on a ton of power behind its Fighting STAB, but it triggers Rocky Helmet/Rough Skin/Iron Barbs with Arm Thrust 5 times in a row. To condense:
-Pin Missile
-Close Combat
-Rock Blast
-Earthquake/Swords Dance
Nature: Adamant
EVs: 40 HP/252 Atk/216 Spe (enough Speed to outrun Adamant Bisharp when Mega)
Item: Heracronite
Ability: Guts/Moxie
Clefable gained the Fairy type in Gen VI. It's no longer a Normal Pokemon, so Facade is useless on it now, especially when its Special Attack got buffed this gen:
-Wish
-Protect
-Moonblast
-Heal Bell/Aromatherapy/Thunder Wave
Nature: Bold
EVs: 252 HP/252 Def/4 SDef
Item: Leftovers
Ability: Unaware/Magic Guard
or
-Calm Mind
-Moonblast
-Stored Power/Flamethrower
-Soft-Boiled/Moonlight
Nature: Bold
EVs: 252 HP/252 Def/4 SDef
Item: Life Orb/Leftovers
Ability: Magic Guard
or
-Stealth Rock
-Moonblast
-Flamethrower
-Soft-Boiled/Moonlight
Nature: Bold
EVs: 252 HP/252 Def/4 SDef
Item: Leftovers
Ability: Magic Guard
or
-Moonblast
-Fire Blast

-Soft-Boiled/Moonlight
Nature: Modest
EVs: 252 HP/252 SAtk/4 SDef
Item: Life Orb
Ability: Magic Guard
You're not taking full advantage of Sableye's Prankster. It needs Taunt so that walls can't set up on it. Fake Out isn't really useful either:
-Taunt
-Will-o-Wisp
-Recover
-Foul Play/Knock Off
Nature: Bold/Impish
EVs: 252 HP/252 Def/4 SDef
Item: Leftovers
Ability: Prankster
Jumpluff is terrible because it seriously lacks offensive presence. It's also outclassed by other Grass Pokemon in supporting roles such as Amoonguss, Chesnaught and even Small Gourgeist:
Amoonguss:
-Spore
-Giga Drain
-Foul Play
-Clear Smog/Sludge Bomb
Nature: Bold
EVs: 252 HP/252 Def/4 SDef
Item: Black Sludge
Ability: Regenerator
Chesnaught:
-Leech Seed
-Spiky Shield
-Hammer Arm
-Wood Hammer/Spikes
Nature: Impish
EVs: 252 HP/252 Def/4 SDef
Item: Leftovers
Ability: Bulletproof
Small Gourgeist:
-Substitute
-Leech Seed
-Will-o-Wisp
-Seed Bomb/Protect
Nature: Jolly/Timid
EVs: 252 HP/32 Def/224 Spe
Item: Leftovers
Ability: Frisk
However, this team is seriously weak to Talonflame. Heatran, Wash Rotom, Tyranitar or Therian Landorus make handy counters to it (this is over Jumpluff):
Heatran:
-Lava Plume
-Protect
-Taunt/Roar/Stealth Rock
-Will-o-Wisp/Toxic
Nature: Calm
EVs: 248 HP/220 SDef/40 Spe
Item: Leftovers
or
-Substitute
-Toxic
-Lava Plume/Fire Blast/Flamethrower

EVs: 252 SAtk/12 SDef/244 Spe
Item: Leftovers
or
-Overheat/Fire Blast
-Flash Cannon
-Stone Edge/Earth Power
-Flamethrower/Fire Blast/Hidden Power (Ice)
Nature: Modest
EVs: 252 SAtk/4 SDef/252 Spe
Item: Choice Scarf
Wash Rotom:
-Volt Switch
-Hydro Pump
-Will-o-Wisp
-Pain Split/Rest
Nature: Bold/Calm
EVs: 248 HP/216 Def/44 Spe (Bold) or 248 HP/216 SDef/44 Spe (Calm)
Item: Leftovers/Chesto Berry
or

Therian Landorus:
-Stealth Rock

or
-Swords Dance

-Earthquake
-Stone Edge
Nature: Adamant
EVs: 48 HP/252 Atk/208 Spe
Item: Leftovers/Earth Plate/Soft Sand
Gothitelle needs the raw power of Choice Specs to eliminate threats because Expert Belt may not be enough on neutral targets and Gothitelle isn't really strong. It can also use Trick to pass on the Choice Specs on to a wall in order to cripple it before taking it out. Gothitelle is meant to switch out once it's done its job, making the locking of Choice Specs a non-issue:
-Psyshock/Psychic
-Thunderbolt
-Hidden Power (Fire)/Energy Ball
-Trick
Nature: Modest
EVs: 252 SAtk/4 SDef/252 Spe
Item: Choice Specs
Ability: Shadow Tag
Noivern's Attack is terrible, meaning physical moves like Acrobatics are a no-go:
-Draco Meteor
-Hurricane
-Flamethrower/Focus Blast
-Roost/Taunt
Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe
Item: Life Orb
Ability: Infiltrator
Since Noivern is weak to Stealth Rock, Defog/Rapid Spin support from Excadrill, Mandibuzz or Skarmory is appreciated:
Mandibuzz:
-Foul Play
-Roost
-Taunt/Whirlwind
-Defog
Nature: Bold
EVs: 248 HP/136 Def/108 SDef/16 Spe
Item: Leftovers
Ability: Overcoat
Excadrill:
-Earthquake
-Iron Head
-Rapid Spin
-Rock Slide/Stealth Rock
Nature: Adamant
EVs: 252 Atk/4 Def/252 Spe
Item: Leftovers/Air Balloon
Ability: Mold Breaker
or
-Earthquake
-Iron Head
-Rock Slide
-Rapid Spin
Nature: Adamant/Jolly
EVs: 252 Atk/4 Def/252 Spe (Choice Scarf) or 120 HP/136 Atk/252 SDef (Assault Vest; Adamant only)
Item: Choice Scarf/Assault Vest
Ability: Mold Breaker
Skarmory:
-Roost
-Defog
-Whirlwind/Taunt/Brave Bird
-Toxic/Stealth Rock/Counter/Brave Bird
Nature: Bold/Impish
EVs: 252 HP/252 Def/4 SDef
Item: Leftovers/Rocky Helmet
Ability: Sturdy
Before you ask, most people don't play with item clause (when all Pokemon must hold different items), so feel free to use multiple Lefties/Life Orbs among your team.
