Need help with my team!

[Ars Arcanum]

I'm having trouble finding three more pokemon that'll fit well into a new team I'm breeding:

@Leftovers/Life Orb
Nature: Timid
Ability: Flash Fire
EVs: 252 SpAtk/252 Spd/4 HP
~Hex
~Will-O-Wisp
~Flamethrower/Heat Wave
~Energy Ball/Confuse Ray

@ Lucarionite
Nature: Timid
Ability: Inner Focus
EVs: 252 SpAtk/176 Spd/72 HP
/8 SpD
~ Nasty Plot
~ Aura Sphere
~ Flash Cannon
~ Shadow Ball/Dark Pulse

@Leftovers/Life Orb
Nature: Modest/Bold
(No moveset figured yet)

Pokemon I'm considering for the next 3 slots: Gyarados, Abomasnow, Mamoswine, Dragonite, Salamence, Aggron, Scizor, T-Tar, Cradily. Though I'm open to any advice.

Thank you in advance :)

Abomasnow could work well in that team to start. It can cover dragons and several other types. The only problem is the 4x weakness to fire, so you might need a fast Mon to quickly take out someone who has a strong fire move. Greninja could do the job, and possibly Gyarados too. Hope this helps!

 

[Super Bling]

An ideal moveset for your Sylveon should be around these lines:

Ability: Pixilate

Hyper Voice, and maybe you move around Wish/Heal Bell support.

In case you didn't know, Pixilate will make Hyper Voice Fairy-Type, as well as giving it a 30% boost. Now I don't know myself if the 30% boost is in addition to STAB, but I'm pretty sure it is.

 

[PlatinumDude]

Chandelure is...okay in OU, but it has better moves to run than Will-o-Wisp + Hex:
-Fire Blast
-Shadow Ball
-Energy Ball
-Trick/Memento/Hidden Power (Ground)
Nature: Timid/Modest
EVs: 4 Def/252 SAtk/252 Spe
Item: Choice Scarf/Choice Specs
Ability: Flash Fire/Infiltrator

or
-Substitute
-Pain Split
-Fire Blast
-Shadow Ball
Nature: Timid/Modest
EVs: 4 Def/252 SAtk/252 Spe
Item: Life Orb/Leftovers
Ability: Flash Fire

Mega Lucario should just use max Special Attack/max Speed. What does it outspeed with your current EV spread? What KOs does it avoid?

Here are possible Sylveon sets for you:
-Wish
-Protect
-Hyper Voice
-Heal Bell/Calm Mind
Nature: Bold
EVs: 252 HP/244 Def/12 Spe
Item: Leftovers
Ability: Pixilate

or
-Hyper Voice
-Psyshock
-Shadow Ball
-Hidden Power (Ground)/Echoed Voice
Nature: Modest
EVs: 244 HP/252 SAtk/12 Spe
Item: Choice Specs
Ability: Pixilate

Since Lucario is taking up the Mega slot, Aggron is out of the equation. Scizor and Tyranitar can still function without their Mega forms.

@willswilly: I highly doubt Abomasnow's effectiveness on this team. Snow Warning got nerfed and its Hail will hinder the rest of the team. However, I can vouch for Gyarados and Mamoswine for team spots:

Gyarados:
-Dragon Dance
-Waterfall
-Earthquake
-Stone Edge/Bounce/Ice Fang
Nature: Adamant
EVs: 252 Atk/4 Def/252 Spe
Item: Life Orb/Lum Berry

or
-Substitute/Taunt
-Dragon Dance
-Waterfall
-Bounce
Nature: Adamant
EVs: 88 HP/192 Atk/4 Def/224 Spe
Item: Leftovers
Ability: Intimidate

or
-Rest
-Sleep Talk
-Waterfall
-Roar/Dragon Tail
Nature: Impish
EVs: 248 HP/252 Def/8 SDef
Item: Leftovers
Ability: Intimidate

Mamoswine:
-Earthquake
-Ice Shard
-Icicle Crash/Ice Shard
-Stealth Rock/Superpower
Nature: Adamant/Jolly
EVs: 252 Atk/4 Def/252 Spe
Item: Life Orb
Ability: Thick Fat

or
-Stealth Rock
-Earthquake
-Ice Shard
-Endeavor
Nature: Jolly/Adamant
EVs: 252 Atk/4 Def/252 Spe
Item: Focus Sash
Ability: Thick Fat

Take note that Gyarados is weak to Stealth Rock, so Rapid Spin/Defog support may be necessary:
Starmie:
-Hydro Pump/Surf
-Thunderbolt/Psyshock
-Ice Beam
-Rapid Spin
Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe
Item: Leftovers/Life Orb
Ability: Natural Cure

or
-Scald
-Rapid Spin
-Psyshock/Ice Beam/Thunderbolt
-Recover
Nature: Timid
EVs: 248 HP/32 Def/4 SAtk/224 Spe
Item: Leftovers
Ability: Natural Cure

Excadrill:

-Rock Slide/Iron Head
-Rapid Spin
-Swords Dance/Stealth Rock
Nature: Jolly
EVs: 4 HP/252 Atk/252 Spe

or
-Earthquake

EVs: 120 HP/136 Atk/252 SDef (Adamant) or 252 Atk/4 Def/252 Spe (Jolly)

Item: Black Sludge
Ability: Infiltrator

Tentacruel:
-Scald
-Sludge Bomb
-Rapid Spin
-Toxic/Knock Off
Nature: Bold
EVs: 252 HP/224 Def/32 Spe
Item: Black Sludge
Ability: Liquid Ooze

 

[Ars Arcanum]

Thanks for all the suggestions!

I definitely want Stealth Rock and Knock Off support, so Mamoswine is an option. Ive also been excited to try Gyarados, he looks so fun. Im guessing its better to run Pixilate/Hyper Voice on Sylveon than Moonblast, then?

 

[Azire]

Yes if you can run Hyper Voice and Pixilate over Moonblast. If you're playing on a simulator there should be no problems. If you're playing on cartridge it will be harder to get.

Pixilate boosts Hyper Voice to 117 BP then you get STAB. Moonblast is only 90BP. If you can't get a Hidden Ability Eevee with Hyper Voice and a competitive IV spread I would use Moonblast with Cute Charm. Pixilate doesn't give any benefit if you aren't using a Normal Type move.

 

[Ars Arcanum]

Bump. I just need a little more. In addition to these:

I'm having trouble finding three more pokemon that'll fit well into a new team I'm breeding:

@Leftovers/Life Orb
Nature: Timid
Ability: Flash Fire
EVs: 252 SpAtk/252 Spd/4 HP
~Hex
~Will-O-Wisp
~Flamethrower/Heat Wave
~Energy Ball/Confuse Ray

@ Lucarionite
Nature: Timid
Ability: Inner Focus
EVs: 252 SpAtk/176 Spd/72 HP
/8 SpD
~ Nasty Plot
~ Aura Sphere
~ Flash Cannon
~ Shadow Ball/Dark Pulse

@Leftovers/Life Orb
Nature: Bold
Ability: Cute Charm
EVs: 252 HP/200 SpA/50 SpDef
~Wish
~Protect
~Moonblast
~Shadow Ball

I now have

Mamoswine @ Focus Sash
Nature: Adamant
Ability: Thick Fat
EVs: 252 Atk/252 Spd
~Stealth Rock
~Ice Shard
~Icicle Crash
~Earthquake

[A Pokemon with Knock Off that isn't Scrafty]

And finally for the last slot, I'm considering either a Gyarados or Salamence. Either Initimidate or Moxie either, all I know is that I want whichever I choose to have DD.

 

[Nah]

Gyarados is the slightly better option over Salamence. Fairies give Mence too much trouble nowadays. 'Sides, Water's often a good type to have.

-Gyarados w/Life Orb
Nature: Adamant/Jolly
Ability: Moxie
EVs: 252 Attack, 252 Speed, 4 Sp.Defense
Moves: Waterfall, Dragon Dance, Earthquake, Stone Edge/Ice Fang

or

-Gyarados w/Leftovers
Nature: Adamant
Ability: Intimidate
EVs: 88 HP, 192 Attack, 4 Defense, 224 Speed OR 156 HP, 72 Atttack, 96 Defense, 180 Sp.Defense, 4 Speed
Moves: Waterfall, Dragon Dance, Bounce, Taunt/Substitute

Also, your Sylveon appears to be trying to do a combination of the sets Platinum posted. Don't do that; trying to do both makes it less effective at either job.

To add to what Zekrom said, refer to the above Chandelure sets for much better alternatives.
