Solrock @ Choice Band ** Matutinus

Adamant Nature (+Atk, -SAtk)

The moveset is fine, though why did you give it so much EVs in speed? You might give it more sp.def EVs because a STAB-bed Surf or any attacks that Solrock is weak to, might OHKO it.

Lunatone @ Leftovers ** Opacare
Trait: Levitate
EVs: 159 HP / 145 Def / 206 Spd
Modest Nature (+SAtk, -Atk) - You forgot to set it.
- Calm Mind
- Hypnosis
- Ice Beam
- Psychic

The moveset is ok, but like I said before at Solrock: less speed EVs, and more sp.def EVs.

Vileplume (F) @ Leftovers ** Tempus Vernum
Trait: Chlorophyll
EVs: 252 HP / 106 Def / 152 SDef
Calm Nature (+SDef, -Atk)
- Aromatherapy
- Hidden Power [Grass]
- Moonlight
- Sleep Powder

Vileplume looks ok, though since this team is for UU/BL, you'll probably meet a few bug pokemons that can cause some problems there. :/

Clefable (F) @ Leftovers ** Stella
Trait: Cute Charm
EVs: 252 HP / 72 Def / 128 SAtk / 58 SDef
Modest Nature (+SAtk, -Atk)
- Calm Mind
- Ice Beam
- Rest
- Thunderbolt

Clefable is fine, but maybe Softboiled would be a better choice over Rest.

Omastar (M) @ Lum Berry ** Aqua
Trait: Swift Swim
EVs: 50 HP / 208 Spd / 252 SAtk
Modest Nature (+SAtk, -Atk)
- Hidden Power [Grass]
- Ice Beam
- Rain Dance
- Surf

Why so much EVs in speed for Omastar? 176 will be ok for him. You might want some defense or maybe sp.defense EVs there.

Altaria (F) @ Leftovers ** Caelum
Trait: Natural Cure
EVs: 150 HP / 184 Spd / 176 SAtk
Modest Nature (+SAtk, -Atk)
- Rest
- Fire Blast
- Dragon Claw
- Haze

It's ok.

I don't bother with major weaknesses, as this isn't my serious team, but if it works well, I may use it.

The movesets are rather standard so there's basically nothing wrong there. Though 5 special attack users and only 1 physical attacker? A special tank can stop this team so you might want to put at least 1 or 2 other physical attackers in it, too.

Anyway, I hope this will help. Well, good luck.

maybe I'll turn Altaria into a DDer.
I'll give Lunatone and Solrock Sp.Defence EVs.
I won't even bother with Sp. Defence on Oma. It can kill Special Sweepers and I've used him before and that Speed is nice, but maybe I'll trade some of it for HP.

Thanks for your help
