My OU team. ADVISE NEEDED

[graves]

Well, I've been doing pretty good with this team, about a 80% win rate.
I would like to get opinion's and idea's to make it better!
Ok so here it is.

The Setup.

Azelf @ Focus Sash
Ability: Levitate
EV's 252 HP/180 Def/76 Spd
Naive nature (+Spe, -SpD)
- Stealth Rock
- Psychic
- Explosion
- Fire Blast
Azelf really helps out my team.
Common lead's like Infernape, Roserade, Tentacruel,
are taken out in two turns (which I can guaranty with focus sash.)
fire blast helps with Bronzong,
Explosion usually OHKO's Gyarados, and I always get a stealth rock off.

The revenge Killer.

Gengar @ Choice Scarf
Ability: Levitate
EVs: 4 Def/252 SpA/252 spe
Modest nature (+SpA, -Atk)
- Shadow Ball
- Thunderbolt
-Trick
-HP Ice
Gengar is a great revenge killer.
A common thing that takes out my Azelf:
Other Gengars, so when they've done their work, I can take out MY Gengar,
and OHKO them.
He's also my main Gyarados, Suicune, Skarmory and Kingdra counter.

The Defensive Sweeper.

Salamence @ Lum Berry
Ability: Intimidate
EVs: 252 HP/180 Def/76 Spe
Jolly Nature (+Spe -SpA)
- Dragon Dance
- Outrage
- Earthquake
- Roost
This is my Physically Defensive Sweepers.
I've been able to get at least one dragon Dance in every time I use him.
Sometimes even two or three,
He sweep's VERY effectively even thought that wasn't this set's intentions.
a Ice beam un-STABBED does around 46%. so I can regain health using roost.
Lum Berry makes Outrage a very key move for late game sweep's,
He has trouble dealing with Scizor, Bronzong and Skarmory though,
which is why I have this next guy.

Mod edit: I'm editing over this useless post to tell you that you need to read the rules and pm me (SoT) with the complete version of the team and I'll unlock and let you edit it in.

Approved by Flashstorm1.

P.S. My post was not useless!

p.s.s from the best sot: yeah it was.
