Is my first ev trained team good?

[LiamRae]

Hello, this is my very first post so sorry if it's in the wrong place etc :3

Mawile ( hp/atk ev trained )
- Play rough
- Sucker punch
- Swords dance
- Iron head

Metagross ( atk/spe ev trained )
- Earthquake
- Metor mash
- Agility
- Zen headbutt

Sylveon ( hp/def ev trained )
- Toxic
- Protect
- Moonblast
- Wish

Umbreon ( hp/spD ev trained )
- Protect
- Confuse ray
- Toxic
- wish

Mienshai ( atk/spe ev trained )
- Hi jump kick
- U-turn
- Stone edge
- Hidden power ice

Charizard ( spA/spe ev trained )
- Fire blast
- Air slash
- Hidden power grass
- Roost

Any tips or advice on the movesets etc would be great, thanks :3

Natures and items would be appreciated here.

Mawile should use its Mega form (it must be holding Mawilite to be effective). The nature and EV spread should be Adamant and 124 HP/252 Atk/132 Spe respectively to outspeed Aegislash and Scizor.

Agiligross isn't as effective as it used to be. Metagross is now best played as a bulky attacker:
-Stealth Rock
-Meteor Mash
-Earthquake
-Trick/Bullet Punch/Pursuit
Nature: Adamant
EVs: 252 HP/252 Atk/4 Def
Item: Iron Ball/Leftovers
Ability: Clear Body

or
-Meteor Mash
-Earthquake
-Bullet Punch
-Zen Headbutt/Pursuit
Nature: Adamant
EVs: 252 HP/252 Atk/4 Def
Item: Leftovers
Ability: Clear Body

While Sylveon is better off with Hyper Voice + Pixilate, (a Pokebank-exclusive combination; Eevee with Hyper Voice must be transferred from B2/W2) Moonblast + Cute Charm is an acceptable alternative. You can also consider Shadow Ball as a coverage option over Toxic. The preferred nature is Bold, by the way.

I wouldn't use Umbreon and Sylveon together, tbh, as one Wish user on the team is generally enough. I feel that you need some speed on the team, and Greninja is the Pokemon that can do that:
-Hydro Pump/Surf
-Ice Beam/Dark Pulse
-Extrasensory/Dark Pulse
-U-turn/Hidden Power (Fire)
Nature: Hasty/Timid
EVs: 4 Atk/252 SAtk/252 Spe
Item: Life Orb
Ability: Protean

or
-Spikes
-Hydro Pump/Surf
-Ice Beam
-U-turn/Extrasensory
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Life Orb/Focus Sash

Mienshao just doesn't cut it in OU; a lot of Pokemon do what it does better, like Lucario:
-Swords Dance
-Close Combat
-Extreme Speed/Bullet Punch
-Crunch/Shadow Claw/Ice Punch
Nature: Jolly/Adamant
EVs: 4 HP/252 Atk/252 Spe
Item: Life Orb

Charizard's Mega forms are what make it good in OU right now. It's seriously lackluster without Charizardite X or Charizardite Y. A Dragon Pokemon like Goodra is better in its place; it synergizes well with Mawile and Metagross:
-Draco Meteor
-Fire Blast
-Sludge Bomb/Thunderbolt
-Focus Blast/Dragon Tail
Nature: Modest/Quiet/Sassy
EVs: 248 HP/252 SAtk/8 SDef
Item: Choice Specs/Leftovers/Assault Vest
Ability: Gooey/Sap Sipper

or
-Dragon Pulse
-Flamethrower
-Focus Blast/Thunderbolt
-Toxic/Dragon Tail
Nature: Calm/Sassy
EVs: 248 HP/8 Def/252 SDef
Item: Leftovers
Ability: Gooey/Sap Sipper

You put this thread in the right place.

Natures, Abilities, and items are important too, so include those as well.

They all seem to be correctly EV trained to me. Thing is, you have Umbreon and Sylveon doing the exact same thing (you have both of them doing a Wish+Protect stall), and there's no point in that. Umbreon can't do much else, so its best to change Sylveon's set:

-Sylveon w/Leftovers
Nature: Modest
Ability: Pixilate is preferred, but if you can't get that, its ok
EVs: 252 HP, 252 Sp.Attack, 4 Defense
Moves: Calm Mind, Moon Blast/Hyper Voice (HV only with Pixilate), Shadow Ball, Hidden Power Fire/Psyshock

Also, swap Umbreon's Confuse Ray with Foul Play (or at least some sort of attack), otherwise it is absolute Taunt bait and set-up bait. Confusion is a bit of an unreliable status effect anyway.

Mawile and Charizard shine in their mega forms, not their regular forms. So they need their Mega Stones. I'm assuming your Charizard will be a Mega Charizard Y. If that's the case, replace Hidden Power with Solar Beam. Since Mega Zard Y has Drought, the sun will be up when its in play (so no charge turn for Solar Beam), and Solar Beam is the superior option since it has double the power of Hidden Power. If you keep Roost on it, you'll need to swap Air Slash with either Dragon Pulse or Focus Blast. Otherwise a lotta stuff will wall it. If its a Mega Charizard X, then a totally different set is needed.

I was assuming that Mawile was using Mawilite when I posted, but since a player can only use one Mega Evolution per battle, that was why I suggested Goodra in Charizard's place.

You should consider replacing Umbreon with a Pokémon that has more HP, such as either Chansey, Blissey, or Vaporeon. They could definitely make better Wish users.

EVs: 252 HP / 248 SDef / 8 Spd
Calm Nature (+SDef, -Atk)

- Heal Bell

Chansey (F) @ Eviolite
Trait: Natural Cure
EVs: 252 HP / 248 SDef / 8 Spd
Calm Nature (+SDef, -Atk)
- Wish
- Thunder Wave / Toxic
- Seismic Toss
- Heal Bell

Vaporeon (M) @ Leftovers
Trait: Water Absorb
EVs: 252 HP / 176 SAtk / 80 SDef
