Background
When it comes down to offense, I usually am the first guy to complain. Ever since the metagame shifted from stall to offense, I have had a hard time adapting. Most of my teams either were too weak to a certain threat, or just got worn out by physical/special sweepers. After a bit of reconsidering, I decided to go back to the classic "BulkyOffensive" teams I used to create and love Unfortunately, this one has a bit of a problem with faster, stronger foes, but can usually manage them over time (I don't, however, have a true answer to DDKingdra and DDMence, which are two huge threats) Oh, and the Chess style theme is because Chess is so much fun ^__^
The Pawn @ Lum Berry
Adamant
240 HP/80 Att/190 SpD
Meteor Mash
Earthquake
Bullet Punch/Reflect/Pursuit
Stealth Rock
Purpose: Like a good pawn, Metagross is there to soften up the opposition and open up sweeps for the rest of my team. It sets up Stealth Rock, counters Gengar, Deoxys-e, etc...and can set up Reflect if I go that route. Meteor Mash is truly awesome; hurting things even with little attack investment. The only thing that really scares me are Heatran leads, which can really hurt. Gyarados is the initial switch in, but if it's an HP Electric version, I can be in serious trouble.

The Bishop @ Choice Scarf
Timid
252 SpA/252 Spe/6 HP
Shadow Ball
Thunderbolt
HP Ice
Focus Blast
Purpose: The Bishop is supposed to be able to move any number of squares diagonally. Considering that ScarfGar is very, very, very fast, it seemed to suit him =] Gengar is a fantastic revenge killer, perhaps the best in the game. He outspeeds Gyarados after 2 Dragon Dances, making him a very reliable check (Adamant Gyara reaches 521 after 2 Dragon Dances, whereas Timid ScarfGar gets to 525). Salamence stands no chance against HP Ice, and Tyranitar is taken out by Focus Blast.

The Rook @ Choice Band
Adamant
252 Att/252 Spe/6 HP
Close Combat
Ice Punch
Stone Edge
Bullet Punch/Extremespeed
Purpose: Choice Band Lucario is such an underrated threat. 2HKOing Skarm, OHKOing Gliscor and Salamence, plus dealing heavy damage to Gengar and Gyarados is all very important. It's also my only "real" safe switch into standard CB Tar. Like a Rook, Luke can move in any number of ways thanks to priority; Bullet Punch or Extremespeed.

The Knight @ Leftovers
Adamant
252 HP/236 Def/22 SpD
Rest
Sleep Talk
Waterfall
Stone Edge
Purpose: Gyarados is an excellent Rest-Talker, especially thanks to Intimidate I always found the Knight to be pretty bulky, I mean, a horse head is pretty strong. EV spread lets me live a +1 LO Stone from foe Gyara even after SR damage. This guy is my main switch into Heatran and such, and is an excellent one at that. Gyara's my only answer to Scizor, therefore, his survival is extremely important.

The Queen @ Leftovers
Quiet
252 HP/60 Att/168 SpA/30 Spe
Substitute
Focus Punch
Flamethrower/Ice Beam/Thunderbolt
Crunch
Purpose: Here it is; the wall destroyer and "queen" of this team. I really love the Boah set, it's fun to use and can really hurt things with a Sub up. This girl is Scizor bait, and, with Flamethrower, it'll rip the steel bug into shreds. Boah also handles many, many more things; Skarmory, Hippowdon, Donphan, Gliscor (if I use Ice Beam), Gyarados, Suicune, Milotic (if I use Thunderbolt) and Celebi, Cress, and Gengar. She's the Queen mainly because she can do anything! Just like a Queen in Chess, she's not limited to hitting certain foes; Focus Punch/Crunch/Flamethrower hits everything in the game for neutral. She's also great to open a sweep for my other Pokes since neither Kingdra nor Luke want to have Hippowdon or Zapdos around.

The King @ Leftovers
Adamant
252 Att/252 Spe/6 HP
Dragon Dance
Waterfall
Outrage
Substitute
Purpose: "SubDra" is my favorite Kingdra set, and, with the word "King" in his name, this is a no brainer (too bad I didn't pick it up that quickly) Hee can use things like Heatran as a free switch in, and also laugh the "#1 Physical Wall in the game" A.K.A Hippowdon. Substitute protects me from status which is really irritating, and, unlike Mence, Kingdra has only 1 2x weakness which is only used by dragon types who get ripped by DD Outrage. By far, my favorite Dragon Dancer thus far.
