Before I made this team, I almost exclusively used an offensive Rain Dance team of some sort. These days, I've switched my RD team to reserve and have been running with the following six, non-central-strategy-dependent, Pokemon. I had wanted to use a pure synergy team for a while (a team that relies on helping each other out opposed setting up RD and sweeping), but I didn't really know how to get one started. I got six Pokemon together, tested them out, made a few modifications, and here's what I've got to show for it. They work well together and have proven themselves, to me at least, to be a fairly strong offensive team. Here they are at a glance:

The Anti-Lead
Earthquakes-Mamoswine
Mamoswine @ Focus Sash
Ability: Snow Cloak

Ice Shard
Endeavor

Earthquakes-Mamoswine

Mamoswine @ Focus Sash
Ability: Snow Cloak
EVs: 4 HP/252 Atk/252 Spd
Adamant nature (+Atk, -SAtk)
Earthquake
Ice Shard
Endeavor
Stealth Rock
I consider the lead to be the most important part of a team. Mamoswine fills the position to perfection by taking out several of the common leads such as Metagross, Aerodactyl, Gliscor, and occasionally Heatran. I say occasionally because most Heatran will switch out immediately, usually to one of those pesky Rotom appliances. Also, Mamo gets rocks up very reliably, as long as he isn't faced with a quick foe who will put him to sleep. As a plus, Mamoswine really puts Taunt users in their place. Aerodactyl, 252 HP/40 Def Gliscor, and Crobat are all safely 2KOed by Ice Shard, so if they try to Taunt me, they get a the nice surprise of dying without setting up anything else. Rain Dance teams that lead with Crobat are especially crippled if Bat goes for the Taunt over RD. Has anyone noticed that this thing in the only Pokemon on my team who hasn't changed one bit? Just thought I would bring that up, as part of the case for why Mamoswine is awesome.
The Wall Breaker
Fire-Infernape
Fire-Infernape

Infernape @ Life Orb
Ability: Blaze
EVs: 64 Atk/192 Spd/252 SAtk
Hasty nature (+Spd, -Def)
Flamethrower
Close Combat
Grass Knot
Mach Punch
Don't even think about commenting on my nicknames just yet. As you read, the theme may reveal itself (but if it doesn't, try a Google search or something).
Anyway, on to what this gorilla does. Infernape is known far and wide for how well he breaks walls on both ends of the spectrum. He usually has to face a stray Blissey or Skarmory for me, and he's perfectly fine with that. Blissey is my team's biggest fear, because I rely very heavily on Special Attack, so MixApe really looks after my team. Mach Punch will help him take out Lucario as well as pick off any weakened foes. Grass Knot was added to deal with Swampert.
The Steel-Killer
Revolution-Magnezone
Revolution-Magnezone

Magnezone @ Choice Scarf
Ability: Magnet Pull
EVs: 40 HP/252 SAtk/216 Spd
Timid nature (+Spd, -Atk)
Thunderbolt
Flash Cannon
Hidden Power Fire
Signal Beam
Okay, I went back to Magnezone because Scizor just wasn't working for my team at all. It really just didn't fit quite right (and I tried a few different sets, just to give him his fair chance). Going back to Magnezone, I can destroy other Steel types while also posing a threat to Gyarados. This will allow me to put Toxic back on Vappy too! Anyways, the Speed allows him to outrun several Steel-type threats, as well as base 110s and under, so Gyarados has to watch out if it doesn't have any DDs under its belt. Signal beam was added instead of Explosion because I rarely (actually never) used it, so this will help me deal with Celebi.
The Water Resist
Sounder-Vaporeon
Sounder-Vaporeon

Vaporeon@ Leftovers
Ability: Water Absorb
EVs: 170 HP/240 Def/68 Spd/32 SAtk
Bold nature (+Def, -Atk)
Surf
Wish
Protect
Toxic
What do all three of the previous Pokemon hate? If you said Surf, you would be right. Ape is doomed if he gets a Surf directed at him, Mamo, although not always, will usually be OHKOed by Surf or Hydro Pump, and let's just say that Magnezone can't take too many of 'em, especially from the likes of Latias and Starmie. So what's the best way to counter stray Water attacks? Vaporeon's Wator Absorb of course! This little puppy can ruin opposing Water types by poisoning and then either stalling or switching. She also works to rid the field of Mamoswine's nightmares: Infernape, Heatran, as well as some of the less common Fire types who think that they actually stand a chance. Wish works well either while stalling or to heal up one of my injured sweepers.
The Boosting Tank
Galaxy-Latias
Galaxy-Latias

Latias @ Lum Berry
Ability: Levitate
EVs: 6 HP/252 Spd/252 SAtk
Timid nature (+Spd, -Atk)
Dragon Pulse
Surf
Recover (Currently testing Psychic)
Calm Mind
This thing can switch in on a water attack, Calm Mind on the switch (provided it isn't a Latias running Dragon Pulse/Draco Meteor or a Starmie running Ice Beam), and then procede to sweep from there, occasionally predicting a switch/Protect in order to Calm Mind up again. I originally had Starmie in its place, but after two matches on Shoddy, Starmie was long gone. Latias gets amazing coverage, (Dragon+Water is only resisted by Empoleon and Shedinja) and it can also take neutral and NVE hits well, giving me a sweeper who is not only powerful, but also durable. Latias has great synergy with Magnezone, she is almost eager to switch into Fire or Fighting moves, and Zone will gladly take a Dragon or Ghost move for the team. With Recover, Latias will be much more durable, able to heal off any extra damage. The Lum Berry is to give my team someone to switch in on a Breloom Spore, as well as just because Latias doesn't like having to switch to Gliscor in the middle of its CM sweep just to avoid paralysis.
The Set-Up Stopper
Dynamo-Gliscor
Dynamo-Gliscor

Gliscor @ Yache Berry
Ability: Hyper Cutter
EVs: 252 HP/216 Spd/42 SDef
Jolly nature (+Spd, -SAtk)
Earthquake
Stone Edge
Roost
Taunt
Gliscor was suggested by Haunter, and I've always wanted to try him out, so here it is. I decided to go with the SD set, but that may change to a set with Taunt so that I can stop stallers. This thing will help me take out Lucario, and it will also provide me will some defense. Combined with Latias, I may not need any more of my team! (Of course I know that isn't true). Anyways, Flygon wasn't really performing his duty as of late so let's hope that Gliscor will take care of some of my problems.
Problems
Breloom: My team, like almost every other, hates 100% accurate sleep. Breloom Spores my Pokemon to sleep and then Sub/Punches its way into victory. Lum Berry on Latias will help with this immensely.Scizor: Again, my team has a stereotypical weakness, this time to Scizor's BP, especially the Banded versions. Latias can come in with Surf, but she fears X-Scissor/U-turn/Pursuit, and Infernape can use Flamethrower, but it will almost always switch. Magnezone will take care of it, but he certainly doesn't want to see a Superpower anytime soon.
Weezing: Luckily, this floating blob of toxicity is rarely seen. However, when he shows up, I have a tough time taking him down due to his defenses (65/120/70). Psychic on Latias would do the trick, but I don't really know what to replace.
Rotom Apps: Yes, I did just make Rotom sound like an iPhone, but who really cares. These annoying little buggers come in at the most annoying of times, burn/Trick my hard-working team, and then leave, only to do it again in the near future. They also hit almost everyone on my team for neutral damage, Scizor being the only resist to their Bolt/Ball combo, but these things know Scizor's weakness, and the problem is; there's an App for that.
Celebi: Celebi really cleans out my team, especially if it has another Pokemon on its side to help it switch and remove poison. Infernape and Magnezone score super effective hits, but the Floating Onion still gives my team trouble.
Latias: Latias hurts my team in the same fashion that my Latias hurts other teams. It CMs up and then sweeps.
Machamp: Who gave this thing permission to be so darn bulky? He really hurts, and it usually takes some sacrificing to take care of him. Psychic on Latias would do the trick, but that doesn't look like its going to happen.
