So this started out as a Battle TOwer team, but when I made it I began to think 'why stop there?' Thus, this team was born!

@ Life Orb (Physical Sweeper)
Steadfast
Adamant
236 HP/252 Atk/20 SDef
Close Combat
Psycho Cut
Night Slash
Thunder Wave
Weak- Flying, Ghost
Gallade was the first Pokemon I decided to have on the team. He's got alright coverage, but Weavile does pretty much the same (if not better) job. T-Wave supports the entire team, slowing down the opponent (Not that many on the team need it).

@ Wise Glasses (Special Sweeper)
Static
Timid
252 SAtk / 252 Spd / 4 HP
Thunderbolt
Flamethrower
Hidden Power (Grass)
Thunder Wave
Weak- Ground
Manectric is my main attacker, only just infront of Weavile. T-Bolt gives STAB, Flamethrower covers Grass, Bug, Ice and Steel really well. Hidden Power deals with Ground and Rock types that resist T-Bolt and Flamethrower (Expecially with a lot of Water/Rock, Water/Ground and Rock/Ground types). Another T-Wave for even more chance of being faster, in case I'm not using Gallade or he gets struck down.

@ Expert Belt (Physical Sweeper)
Pressure
Jolly
252 Atk / 252 Spd / 4 Hp
Ice Punch
Night Slash
Brick Break
Swords Dance
Weak- Fighting, Rock, Bug, Steel, Fire
Ah, here we are. The main source of power. One Swords Dance and Weavile can sweep almost anything. It can OHKO a Dragonite without any HP or Def EVs without a Swords Dance. Ice Punch and Night Slash are STAB with a nice coverage. Brick Break deals with the Rock and Steel types which are slower than Weavile (most are) because those types can deal some great damage on Weavile with its poor Defense stat.

@ ??? (Physical Wall)
Sand Veil
Impish
252 HP/4 Atk/252 Def
Earthquake
Stone Edge
Taunt/Stealth Rock
Roost
Weak- Ice, Water
My Wall. Weak to a few things, but they common Ice types can pack a punch. Plan here is to Stealth Rock so if the opponent were to switch into an Ice type they'd get a nice hit, also scares the opponent from swithing. EQ gives a wide range of coverage and also gets STAB, Roost is a great healing move since t actually reduces Gliscor's 4x weakness to Ice for a turn so with some nice prediction, GLiscor may survive an Ice attack.

@ Leftovers (Baton Passer)
Swarm
Impish
252 HP/112 Def/144 Spd
Swords Dance
Baton Pass
Substitute
X-Scissor
Weak- Fire
My main source of support. Set up a Sub and then Swords Dance before passing it off to someone else. X-Scissor is a nice little STAB move to combat any Grass types that try to do some setting up of their own. Not much more than a Sub-Passer

@ Focus Sash (Special Sweeper)
Speed Boost
Modest
252 SAtk / 4 Def / 252 Spd
Protect
Bug Buzz
Air Slash
Shadow Ball
Weak- Fire, Flying, Rock, Ice, Electric
My last Pokemon. I needed the help of a Flying type for the rather often occurence of Heracross (Since this team may still be used in the Battle Tower). Protect the first turn to get a nice boost in speed before beginning the sweep! Shadow Ball supplies a Special Ghost move that can hit the more Defense orientated Ghosts and Psychics. Bug Buzz can also hit the Psychics and gets a STAB. Air Slash is another STAB move and can hit a fair few types.
Yeah... Somethings need fiddling and tweaking but the generally idea was a team of faves, although Houndoom is a sub and not actually on the team
