[Alter Ego]

Salamence (M) @ Leftovers
Trait: Intimidate
EVs: 116 HP / 252 Atk / 140 Spd
Adamant Nature (+Atk, -SAtk)
- Dragon Dance
- Earthquake
- Flamethrower Fire Blast
- Hidden Power [Flying]

A rule of thumb: Never, EVER use sucky neutral natures. On NB you really need to push your pokémon's abilities to the limit, and without that 10% stat boost it's not going to happen. Just drop Flamethrower for Fire Blast and the little drop in SAtk shouldn't be a bother.

Ludicolo (M) @ Leftovers
Trait: Swift Swim
EVs: 252 HP / 36 SAtk / 220 SDef
Calm Nature (+SDef, -Atk)
- Giga Drain Hidden Power [Grass]/Ice Beam
- Leech Seed
- Surf
- Toxic/Substitute

More like HP Grass since you're going all stally with it. Higher PP and base damage > pitiful HP recovery. Ice Beam is also an option over one of the damaging moves to hit Mence on the switch, and Substitute could be a useful predictionary measure over Leech Seed since you don't want to be forced to switch whenever a physical sweep jumps in.

Skarmory (M) @ Leftovers
Trait: Keen Eye
EVs: 252 HP / 88 Atk / 84 Def / 84 Spd
Impish Nature (+Def, -SAtk)
- Rest
- Spikes
- Steel Wing Drill Peck
- Whirlwind

Bleah, Steel Wing. More like Drill Peck imo, it has better type coverage and is the mortal enemy of Hera. I prefer subskarm but to each their own.

Alakazam (M) @ Choice Band
Trait: Synchronize
EVs: 112 HP / 252 Spd / 146 SAtk
Timid Nature (+Spd, -Atk)
- Fire Punch
- Psychic
- Recover Calm Mind
- Trick

Meh, Zam...don't bother with Recover, it doesn't have the defenses for it. Calm Mind is a far cooler and more useful option. Great for exploiting CBed victims, at least when you don't know what's coming. Also, it could use more SAtk, I think, but I'm not that good with Zam's EVs. >.<

Swampert (M) @ Leftovers
Trait: Torrent
EVs: 252 HP / 136 Def / 120 SAtk
Relaxed Nature (+Def, -Spd)
- Earthquake
- Ice Beam
- Roar
- Surf Rest

With no real prospects for healing, a wall like Swampert needs Rest to survive.

Snorlax (M) @ Leftovers
Trait: Immunity Thick Fat
EVs: 108 HP / 200 Def / 200 SDef
Adamant Nature (+Atk, -SAtk)
- Body Slam
- Curse
- Earthquake
- Rest

Eww...Curselax... .___. Thick Fat over immunity, because ice attacks are much more common than Toxic in the OU. The STalker is so much cooler than this, though. Besides, you've got a status weak which it would ease a bit:

Snorlax @ Leftovers
Trait: Thick Fat
EVs: 240 HP / 152 Atk / 116 Def
Impish Nature (+Def, -SAtk)
Double-Edge
Earthquake/Shadow Ball
Rest
Sleep Talk

Suggestions?

Big-arse status weak because you lack both cleric and STalker. A Jynx played right could sweep through this whole team, I'm afraid. You also seem to rely quite heavily on setups, maybe CB Sala over the DD build for a quick sweeping type. Also, cleric Celebi over Ludi might not be a bad idea considering the kind of havoc that status effects wreak on this team. Ehh...that's all I can think of at the moment, although I have the distinct feeling that there's something fishy with the EVs.

Yeah I changed the natures and gave rest over roar on Swampert. I don't really use it... I used aerial ace over, wouldn't allow drill peck. Used fireblast over flame thrower on salamence, good idea on that. I didn't replace anything on Snorlax, it's quite good as it is actually. And finally I left the recover, its good as it keeps me alive against blisseys.
