Rate my team, please

[bang bang]

Weavile @ Life Orb
Jolly
252 Attack, 252 Speed, 4 HP
Ice Punch
Ice Shard
Night Slash
Brick Break

I used to have pursuit instead of ice shard, but a couple of choice scarf pokemon screwed me over so I switched. Gets rid of Jolly Garchomp, Timid Gengar, Azelf, and outspeeds dragon dance Tyranitar after one boost.

Salamence @ Focus Sash
Adamant
252 Attack, 252 Speed, 4 HP
Dragon Claw
Earthquake
Stone Edge
Dragon Dance

With 404 Attack, she's already a big threat, but with a dragon dance, she's nigh unstoppable. The main sweeper of the team, she has more freedom after Weavile removes most of her counters.

Gyarados @ Leftovers
Adamant
252 Attack, 252 Speed, 4 HP
Waterfall
Earthquake
Ice Fang
Dragon Dance

A single dragon dance lets Gyarados outspeed most everything that isn't wear a choice scarf, and some that are (which is what the extra speed EV's are for). Great for switching into choice scarf Heracross, who would otherwise give this team a real problem.

Electivire @ Expert Belt
Adamant
252 Attack, 252 Speed, 4 HP
Thunderpunch
Ice Punch
Earthquake
Cross Chop

Fast electric pokemon like Jolteon, seeking to kill Gyarados, just give a boost to Electivire, who knocks them out with an EQ. Formidable with or without the speed boost.

Gengar @ Black Sludge
Timid
252 Special Attack, 252 Speed
Shadow Ball
Focus Blast
Subsitute
Hypnosis

If the opponent is likely to switch out, throw up subsitute. If they're gonna stay in, use hypnosis (and then substitute). With black sludge, he stays in for a while, dealing damage all the while.

Cresselia @ Leftovers (Lum berry if there is item clause)
Impish
252 HP, even between Spec. Defense and Defense
Lunar Dance
Moonlight
Toxic
Psycho Cut

Two main uses-stall while waiting for toxic damage to accumulate, or use Lunar Dance to recover another pokemon. Lunar Dance works great with the rest of the team-heals a 1 HP Salamence, heals Gengar after quite a few substitutes, heals Electivire (who will usually survive a STAB'ed attack, especially special ones), etc... Works really well against Blissey, who expects Charge Beam/Ice Beam.

The end.

Then you need to have an alternate method, not much of a need for Ice Shard just to kill ONE Pokemon -_-'
If anything, I still think you need Pursuit, so put it over Night Slash.

Salamence @ Focus Sash
Adamant
244 Attack, 176 Speed, 88 HP
Dragon Claw
Earthquake
Fire Fang / Fire Blast
Dragon Dance
With 404 Attack, she's already a big threat, but with a dragon dance, she's nigh unstoppable. The main sweeper of the team, she has more freedom after Weavile removes most of her counters.
Speed Overkill. Only needs 255 Speed Minimum or 280 Speed Maximum to begin with.
Also, you need Fire Blast or otherwise, Skarmory and Forretress will just come in and force you to switch.

Gyarados @ Leftovers
Adamant
168 HP / 76 Atk / 88 Def / 176 Spd
Waterfall
Stone Edge
Taunt
Dragon Dance
A single dragon dance lets Gyarados outspeed most everything that isn't wear a choice scarf, and some that are (which is what the extra speed EV's are for). Great for switching into choice scarf Heracross, who would otherwise give this team a real problem.
The above is how cool and original people run their Gyarados. Also, having 2 Dragon Dance attackers is too much overkill.

Electivire @ Expert Belt
Lonely
232 Atk / 216 Spd / 60 SAtk
Thunderbolt
Ice Punch
Earthquake
Cross Chop

Fast electric pokemon like Jolteon, seeking to kill Gyarados, just give a boost to Electivire, who knocks them out with an EQ. Formidable with or without the speed boost.
Thunderbolt KOs Skarmory. The end.

Gengar @ Choice Specs
Timid
252 Special Attack, 252 Speed
Shadow Ball
Focus Blast
Thunderbolt
Energy Ball

If the opponent is likely to switch out, throw up subsitute. If they're gonna stay in, use hypnosis (and then substitute). With black sludge, he stays in for a while, dealing damage all the while.
Gengar isn't awesome enough for Substitute anymore.
Specs with Energy Ball is where it's at. If you still want Hypnosis, use Wide Lens.

Cresselia @ Leftovers (Lum berry if there is item clause)
Impish
252 HP, even between Spec. Defense and Defense
Lunar Dance
Moonlight
Toxic
Psycho Cut

Two main uses-stall while waiting for toxic damage to accumulate, or use Lunar Dance to recover another pokemon.

I'm lost on Cresselia, so someone else can deal with that

The end.

I know the best defense is a good offense, but this team is WAY too oriented on Offenese. You need some walls.

If you want to be on the offense when picking walls, Donphan or Hippowdon make fantastic Physical Walls, and they can attack with destructive force as well.

Special Wall, Snorlax is the best since he can hit hard, and absorb status like nothing. Blissey is also useful if you want to heal the party.

 

[El Gofre]

I cant stop for a full rate, but this tean is way too physical. 4 physical sweepers is absolute overkill. Swap two for another special attacker and another wall.

 

[Azonic]

Agreed. This team is far too physical oriented. Only one pokemon on this team has a special move, and thats the special sweeper. And also far too sweeper oriented. The only defensive pokemon you have is Cresselia, which I personally wouldn't depend on for dual walling. You need some more defensive types.

 

[Random Guy]

I see that this guy is really into speed. If you want, you should use Jolteon and Starmie as special sweepers. Switch one of your DD pokemon for a wall as well.
