Stall is the way to go

[verycoolguy]

Aerodactyl @ Focus Sash
Jolly
Pressure
252 Atk / 252 Spe/ 4 HP
Taunt
Stealth Rock
Rock Slide
Earthquake

The suicide lead. Anyone who sets up gets Taunted, then I lay Stealth Rock. If I'm facing a Lead Metagross I use Stealth Rock right away. Rock Slide for a little damage and the chance to Flinch. Earthquake for good coverage.

Skarmory @ Shed Shell
Impish
Keen Eye
252 HP / 224 Def / 32 Spe
Brave Bird
Spikes
Whirlwind
Roost

A physical wall and a Spiker. Lay Spikes, Roost when necessary, and Whirlwind to rack up damage or to stop set ups. Brave Bird is a strong move to occasionally attack weaker Pokemon. Roost to heal the recoil. If I encounter special attackers, I shall switch to...

Blissey @ Leftovers
Bold
Natural Cure
252 Def / 80 SpA / 176 SpD
Wish
Protect
Toxic
Flamethrower

The Special Wall! Toxic spreads unwanted status, Flamethrower hurts Steels that are unaffected. Wish for healing herself or a teammate. Protect to ensure a safe Wish and to stall for Toxic damage and Leftovers Recovery. If I have trouble with Physical attackers I can switch to Skarmory, or if I predict a hard Fighting move, I switch to...

Dusknoir @ Leftovers
Impish
Pressure
252 HP / 80 Atk / 176 SpD
Gravity
Will-o-Wisp
DynamicPunch
Shadow Sneak

The Spin Blocker. It's a tank that spreads the status of Burn and Confusion. Gravity makes Will-o-Wisp have a 100% accuracy while DynamicPunch has 82%. Fighting and Ghost offer great coverage. Gravity deals with Bronzong who won't get hurt by anything else on my team. I shall try to keep him in to Pressure stall out the PP of strong attacks. I will do so by continuous confusion.

Hippowdon @ Leftovers
Careful
Sand Stream
192 HP / 64 Def / 252 SpD
Earthquake
Stockpile
Roar
Slack Off

Stockpile makes Hippowdon a massive mixed wall. With one Stockpile, it'll be really difficult to take him down. Since I can heal myself with Slack Off, getting in another Stockpile will be easy, and then another one. I spam Roar to damage Pokemon with entry hazards and to shuffle them up. Earthquake to hit Rocks and Steels who won't suffer from Sandstorm damage.

Shuckle @ Ganlon Berry
Impish
Gluttony
252 HP / 200 Def / 56 SpD
Encore
Rest
Knock Off
Toxic

The End Wall. The Sandstorm boosts his Special Defense by 50%. I use Knock Off to nerf opponents by removing their items, unless they are holding a Life Orb. I use Toxic to spray status. I predict the opponents move, and Encore any move that does not harm me a lot. Rest off any damage after the Ganlon Berry activates, and wait until Toxic kills the opponent, and/or the Life Orb recoil catches up.

252 Atk / 252 Spe/ 4 HP
Taunt
Stealth Rock
Rock Slide
Ice Fang

The suicide lead. Anyone who sets up gets Taunted, then I lay Stealth Rock. If I'm facing a Lead Metagross I use Stealth Rock right away. Rock Slide for a little damage and the chance to Flinch. Ice Fang for a chance to Freeze or Flinch, or for Super Effective damage.

EVs aren't very efficient, you don't need nearly that much speed. 136 and a +nature is enough to outspeed Azelf.
Ice Fang is bad. What do you do against Azelf? Jirachi? Metagross? Bronzong? Tyranitar?

Blissey @ Leftovers
Bold
Natural Cure
252 Def / 80 SpA / 176 SpD
Wish

Blissey is a terrible Pokemon and you are a horrible person for using it.

Gimmicky, but usable. Lack of a recovery move is bad for a stall team, though. Even Pain Split is horribly unreliable, I don't recommend using Dusknoir.

Toxic Spikes is the staple of stall teams, I highly recommend a Roserade lead, Drapion, or Tentacruel. Hippowdon can set up Stealth Rock.

-EVs aren't very efficient, you don't need nearly that much speed. 136 and a +nature is enough to outspeed Azelf.
I want to be as fast as possible. If I remove Speed EVs, where do I put them? HP? Adding bulk would make Focus Sash less valuable.

-Ice Fang is bad. What do you do against Azelf? Jirachi? Metagross? Bronzong? Tyranitar?
I guess I can change Ice Fang for Earthquake. Azelf will get hurt harder by Rock Slide anyway.

-Blissey is a terrible Pokemon and you are a horrible person for using it.
Stalling is fun.

After any physical attacker gets burnt and confused, I'd say it's safe to switch in Blissey and pass a Wish. Therefore he gets recovery.

-Toxic Spikes is the staple of stall teams, I highly recommend a Roserade lead, Drapion, or Tentacruel. Hippowdon can set up Stealth Rock.
I do not use Toxic Spikes because I may lose my Spiker before it lays the second layer, so instead of increasing damage each turn, it's 1/8 of HP is not very threatening. If Toxic Spikes are used, then Pokemon who Blissey would like to be Burnt will lose that chance and instead will be Poisoned. I have two Pokemon who use the move Toxic anyway, which will also hit non-grounded Pokemon.

Go Adamant, at least.

And I guess Toxic Spikes is more a playstyle thing for you, then. Whatever works.

Taunt Gyarados ruins your team, as it can easily get up a Dragon Dance against several of your Pokemon.

 

[Blitz Falcon]

About half your team, looks like an obistall. Nothing wrong with that, just saying
