I put this team together not long ago to test it out. It's worked very well! It has taken down many strong Sandstorm and Rain teams as well as others. Anywho, enjoy.
JUST FOUND OUT SHADOW TAG CHANDALURE IS UBER! LOOKING FOR A REPLACEMENT!

Earthquake
Ice Beam
Stealth Rock
Roar
At first my lead was Heatran, and when that opened up way too much of a fighting/ground weakness, I went to Swampert. I needed a little extra help with Garchomp and the likes anyway. Usually gets the rocks set up and maybe kills a pokemon; doesn't last long though. If I see I'll need it later, I'll switch it out, but usually it dies off early.

Leech Seed
Spikes
Power Whip

My replacement for the late Chandalure. Good seeder, spiker, defender. Helps the team out a lot. What more could be said about it, really? It's a stall beast!

Jirachi @ Leftovers
Serene Grace
Bold
252 HP, 216 Def, 52 SDef
Thunderbolt
Psychic
Calm Mind
Wish
I LOVE this thing in the middle of my team. After anthing threatening is taken out, this thing can come in, set up and sweep, or stall, or pass a wish. Good Lord, Jirachi is just a great pokemon! Provides needed synergy.

Hydreigon @ Choice Scarf
Levitate
Modest
4 HP, 252 SAtk, 252 Spe
Draco Meteor
Dark Pulse
Flamethrower
Focus Blast
Have to be careful how I use this one. It isn't overly fast, but it can take a hit sometimes and retaliate BIG. Draco Meteor hits nearly everything hard, Dark Pulse gets stab and hits all psychics and ghosts hard, Flamethrower for anything that Chandalure can't catch, and Focus Blast just reigns on T-tar and the likes.

Starmie @ Choice Specs

Surf
Thunderbolt
Ice Beam
Trick
Usually this thing comes in late. I've had it as my last pokemon before and despite having specs, it swept four pokes in a row. This think also outspeeds and kills Garchomp, Mence, and Dragonite, who I need out of the way ASAP! Might be my favorite on the team, just because it comes through every single time. I can usually only get it in after one of mine faints, but I guess you gotta give one up to kill your opponent.
Conkeldurr @ Leftovers
Guts
Adamant
120 HP, 212 Atk, 176 SDef
Bulk Up
Drain Punch
Mach Punch
Stone Edge
Just look at this guy. Yeah... he is scary. In the beginning, I built the team around this guy. He can take several hits, and hit back even harder, has a recovery move that hits hard, a priority move, and Bulk Up, making him even sturdier. He's almost every aspect of a team himself. Though he doesn't play very "pretty", he does his job, and very well. Just an all around beast. And he has two stone slabs for weapons.. Yeah.
