Fly is too easily played around competitively. It's not worth bothering. Here are much better sets for Charizard to use. Use physical moves only for Charizard X. The only physical move Charizard Y should use is Earthquake:
-Dragon Dance
-Flare Blitz/Fire Punch
-Dragon Claw/Outrage
-Earthquake/Roost/Swords Dance
Nature: Jolly/Adamant
EVs: 252 Atk/4 Def/252 Spe
Item: Charizardite X
Ability: Blaze
Or
-Fire Punch/Earthquake
-Dragon Tail
-Will-o-Wisp
-Roost
Nature: Jolly
EVs: 248 HP/84 SDef/176 Spe
Item: Charizardite X
Ability: Blaze
Or
-Fire Blast
-Solar Beam
-Dragon Pulse/Focus Blast
-Earthquake/Roost
Nature: Mild/Hasty/Modest/Timid
EVs: 4 Atk/252 SAtk/252 Spe
Item: Charizardite Y
You can only Mega Evolve one Pokemon per battle. Having two Mega Pokemon is inefficient. Instead this team needs Rapid Spin/Defog support for Charizard and Staraptor is preferred over Ampharos's slot. Use either one of these:
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:
-Earthquake
-Rock Slide/Iron Head
-Rapid Spin
-Swords Dance/Stealth Rock
Nature: Jolly
EVs: 4 HP/252 Atk/252 Spe
Item: Leftovers/Air Balloon/Chople Berry
Ability: Mold Breaker
or
-Earthquake
-Iron Head
-Rock Slide
-Rapid Spin
Nature: Adamant/Jolly
EVs: 120 HP/136 Atk/252 SDef (Adamant) or 252 Atk/4 Def/252 Spe (Jolly)
Item: Assault Vest (Adamant)/Choice Scarf (Jolly)
Ability: Mold Breaker
Mandibuzz:

Nature: Bold
EVs: 252 HP/224 Def/32 Spe

Really, Lapras isn't that good. Its defensive typing is poor, leaving defensive stats out of the equation. Wash Rotom is a better alternative because it counters Talonflame:
-Volt Switch
-Hydro Pump
-Will-o-Wisp
-Pain Split/Rest
Nature: Bold
EVs: 248 HP/216 Def/44 Spe
Item: Leftovers/Chesto Berry
Or
-Volt Switch
-Hydro Pump
-Thunderbolt/Pain Split/Hidden Power Ice
-Will-o-Wisp
Nature: Modest
EVs: 228 HP/60 SAtk/220 Spe
Item: Leftovers
Or
-Volt Switch
-Hydro Pump
-Thunderbolt/Hidden Power Ice
-Trick
Nature: Timid/Modest
EVs: 4 Def/252 SAtk/252 Spe
Item: Choice Specs/Choice Scarf
Really, I don't think that Zoroark is that viable anymore because of its Fairy weakness. Bisharp is a better alternative because it threatens Fairies:
-Sucker Punch
-Knock Off
-Iron Head
-Swords Dance/Substitute
Nature: Adamant
EVs: 4 HP/252 Atk/252 Spe
Item: Black Glasses/Dread Plate/Leftovers
Ability: Defiant
Metagross is best played as an Assault Vest user. But I think that having 2 Steels is kinda problematic since I suggested Bisharp because of how Bisharp and Metagross share weaknesses. An alternative is Goodra:
-Draco Meteor
-Fire Blast
-Thunderbolt/Sludge Bomb
-Focus Blast/Dragon Tail
Nature: Modest/Quiet/Sassy
EVs: 248 HP/252 SAtk/8 SDef
Item: Assault Vest
Ability: Gooey/Sap Sipper
If you want to keep Metagross, use this set instead:
-Meteor Mash
-Bullet Punch
-Earthquake
-Zen Headbutt/Pursuit
Nature: Adamant
EVs: 252 HP/252 Atk/4 SDef
Item: Assault Vest
Ability: Clear Body
Aerial Ace is a weak move. It only sees use on Mega Aerodactyl because it benefits from Tough Claws. Staraptor is best used with Talonflame, as both can wear down each other's counters together. But if you insist :
-Double-Edge/Return
-Brave Bird
-Close Combat
-U-turn
Nature: Adamant/Jolly
EVs: 252 Atk/4 Def/252 Spe
Item Choice Band/Choice Scarf
And just saying but you don't need to say your Pokemon's IVs, stats and characteristics. Only the natures and EVs matter.
