I've been working on a team! :O Here it is:
At a glance:
Aerodactyl@Focus Sash
252 speed, 252 attack, 4 HP
Jolly
Pressure
-Taunt
-Stealth Rock
-Stone Edge
-Earthquake
Aerodactyl is a common and predictable lead, but gets the job done nonetheless. The speed EVs are there to compliment Aerodactyl's already high speed, almost ensuring a first move aongst most common leads. I use taunt first, to prevent my opponent frm setting up SR, spikes, putting me to sleep, or any other of those annoyances. I then set up SR. The Focus Sash guarantees that I am able to get at least two turns in, unless the lead I am facing is extremely fast. Earthquake and Stone Edge are there in case I'm facing something weak against ground or rock. If not, I switch out and save Aerodactyl for later.
Togekiss@Leftovers
252 speed, 252 HP, 4 defense
Calm
Serene Grace
-Thunder Wave
-Air Slash
-Roost
-Aura Sphere
Togekiss is a great tank, and it can dish out a notable amount of damage as well. However, even with 252 speed EVs Togekiss still can't outspeed too many things. This is where T-wave comes in. Not only will paralysis make the opponent less likely to attack, but it will drastically reduce their speed, allowing Togekiss to outspeed most things. Roost and Leftovers will allow Togekiss to tank, along with the HP EVs. Air Slash has a naturally high 30% chance to make the opponent flinch, which Serene Grace doubles, meaning there's only a 40% chance the opponent will attack. Aura Sphere is, to be honest, only there because I had no idea what to put there and that's what a lot of the Smogon guides on Togekiss said. But I suppose it could help against ice and dark types, for example.
Scizor@Choice Band
248 HP, 252 attack 8 speed
Adamant
Technician
-Bullet Punch
-Superpower
-Pursuit
-U-turn
Scizor is my revenge killer/late-game sweep. because of bullet punch, he's great for finishing opponents near death. And with Technician, an adamant nature, and all those attack EVs, Bullte Punch'll do a bunch of damage. The HP EVs are there to give Scizor the capability to take a few hits. U-turn allows me to scout out my opponents counter, and then deal a bit of damage to it. Superpower so I don't get walled by Steel Types, and it can help me take down Blissey.
Tentacruel@Focus Sash
252 HP, 120 defense, 136 speed
Calm
Liquid Ooze
-Toxic Spikes
-Surf
-Rapid Spin
-Haze
My replacement for Crobat. Still gaurantees getting a haze in, because of Focus Sash, but an take a few more hits, due to higher base HP, and EVs in HP and defence. He can also get rid of Stealth Rock and spikes, with Rapid Spin, and can even take out the occasional opponent with surf. Another reason I replaced Crobat with him is that it cut down on my massive weakness to ice and rock because of the large amount of my team which is flying type.
Salamence@Choice Band
252 attack, 4 HP, 252 speed
Jolly
Intimidate
-Outrage
-Aqua Tail
-Fire Fang
-Earthquake
Salamence is there mainly because he's really powerful, and he can cover a lot of types which the rest of my pokemon can't. Earthquake is there to take care of electric types, since a good part of my team is made up of flying types. It also allows me to get rid of pesky fire-types, as does Aqua Tail. Sure, Celebi and Aerodactyl can take out fires, but after setting up there's a good chance Aerodactyl's dead, or near dead, and Celebi is grass type. Outrage is just an extremely powerful move which allows for me to take care of most opponents in one or two hits. Fire Fang helps me against Skarmory and other Steel types. Choice Band and the attack EVs let him deal even more damage, and the speed EVs make it so he won't be easily out speeded.
Celebi@Choice Scarf
100 HP, 252 SpA, 156 speed
Timid
Natural Cure
-Leaf Storm
-Earth Power
-Psychic
-Trick
Celebi helps cover a lot of types the rest of my team doesn't, and, since it's scarfed and has some speed EVs, can out-speed a lot of things. The SpA EVs are pretty self-explanatory, and the HP EVs let it take a few hits. Natural Cure means if it's put to sleep, frozen, burned, or poisoned, I can just switch it out and not have to worry about that later. Leaf Storm takes out Water types, which I don't have many moves that are good against, Trick screws Blissey over, Earth Power gets rid of electrics, and psychic can help against fighting types.

Well that's my team. o.0 The biggest problem I see atm is that I have so many Flying types. Help me if you can! :D
Changes are in bold.
