[DMFG]

Interesting format. I'm going to assume you mean [IV]/[EVs], with ? indicating lack of EVs..

Vaporeon 31/4-?-31/252-?-31/252-?
Calm-Leftovers
Surf
Ice Beam
Haze
Wish

Vaporeon isn't a great special tank thanks to Tbolt weakness. On the other hand, with things like Stone Edge CBtar and EQ CBchomp running around, he's completely useless as a physical tank. Even with max HP and Def, Bold, you're in danger of being 2HKOd by too many physical threats.

If you really want him as a tank, go something like Calm, 188 HP, 64 Sp Atk, 252 Sp Def and put Protect over Haze. Mind you, you have Blissey so this guy is kinda redundant..

Blissey 31/4-?-31/252-31/252-?-?
Modest-Leftovers
Thunderbolt
Ice Beam
Aeromathearopy
Softboiled

Calm Mind Blissey works significantly less well when you don't actually have Calm Mind on the set. Either drop Tbolt for Seismic Toss or put Calm Mind over Aromatherapy. Bold is better.

Dusknoir ?-31/252-31/252-?-31/4-?
Impish-Leftovers
Focus Punch
WOW
Pain Split
Night Shade

Am I reading this right? Max Attack and def, 4 in Sp Def? Max Attack is pointless when your only attack is Focus Punch and you have no way of preventing people from attacking you. Max def is pointless when you've got nothing in HP.

Um, I'm really not sure what you're trying to do with this guy

Starmie 31/4-?-?-31/252-?-31/252
Modest-Choice Scarf
Surf
Thunderbolt
Ice Beam
Rapid Spin

With no kind of recovery and a Choice item, Rapid Spin won't work. If you want to spin you'll really need at least either Recover or a more defensive spread, and ideally both. Of course, the catch-22 is that that leaves no room for Rapid Spin itself. Again you need to decide what you want this guy to do

Heracross 31/4-31/252-?-?-?-31/252
Adament-Choice Scarf
Megahorn
Close Combat
Pursuit
Earthquake(maybe Stone Edge)

Hera wants Stone Edge in the last slot. This will make a better lead than Vaporeon

Salamence 31/152-31/100-?-?-?-31/252
Jolly-Leftovers
Roost
Dragon Dance
Dragon Claw
Earthquake

Absolute max speed is not necessary when you have DD. 270 speed is a good number to aim for as you outspeed Heracross at that point, for which go Adamant, max attack, enough speed to reach 270 and the rest in HP. I don't like Roost - I don't think you can afford to lose the coverage from your last moveslot for it, by which I mean Flamethrower to hit Skarm and Bronzong.

I have to be honest, this team needs serious re-thinking. You can't just post 6 pokes and expect people to rate it - we can't read your mind and so we don't know what you want each poke to do, what you expect of it.

After each poke, unless it's a complete standard like Scarfcross, write something like "this counters X, and passes Wishes to whatever", or something. Otherwise you'll end up with suggestions that have nothing to do with what you wanted the team to look like.
