Play with your favorites! This team probably isn't the most efficient at doing its job, but I kind of like the members themselves and was hoping to get a critique on its movesets. Thanks.
Edit : I'm willing to make more changes though I'd like not to see an entirely new team. Haha.
(Changes in bold)

Gallade (M) @ Lum Berry
Ability: Steadfast
EVs: 64 HP/252 Atk/192 Spd
Adamant nature (+Atk, -SAtk)
- Close Combat
- X-Scissor
- Hypnosis
- Thunder Wave

Lead Status Gallade. It replaced my Mismagius which really did the same job, but Gallade has been more effective at the lead spot so far. Most people expect the double status and wait a turn for me to Twave to switch so I usually take the opportunity to bring Lapras in to DD or Steelix in SR. He makes a neat lead.

Lapras (M) @ Lum Berry
Ability: Water Absorb
EVs: 144 HP/252 Atk/112 Spd
Adamant nature (+Atk, -SAtk)
- Dragon Dance
- Waterfall
- Return
- Ice Shard
---
DD Lapras. I try to switch in on bulky waters (Vaporeon, Suicune, etc) and DD up while they CM or Wish. I usually win those fights. Lum Berry is good so I can get an extra DD in while they try to status. It's also a good revenger killer for dragons. Which is the reason I put Ice Shard on a DD set. That, and I need a priority move on this team. I don't know why people are so ashamed of being swept by this. Water/Normal is a neat attacking combo. Waterfall flinch hax ftw.

Steelix (M) @ Leftovers
Ability: Sturdy
EVs: 252 HP/120 Atk/136 SDef
Impish nature (+Def, -SAtk)
- Stealth Rock
- Earthquake
- Roar
- Explosion
---
Physical Wall. Standard. I know Skarmory is probably more efficient at this, but I have a thing for Steelix. Haha. I get in on a non fighting/ground move, set up SR, and retreat. Occasionally, I get in an explosion as an opponent tries to stat up because they predicted a switch. I've really only ever killed a few Jirachi's, Vires, and Raikou's with EQ. Everything else, it has to explode to death.

Swellow (M) @ Flame Orb
Ability: Guts
EVs: 252 Atk/252 Spd/4 SDef
Jolly nature (+Spd, -SAtk)
- Brave Bird
- Pursuit
- U-turn
- Facade
---
Guts Swellow. Boy, is this thing fun. If I can knock out the opposing team's steel/priority move pokeys, it's all over. I don't have protect because I can usually get it in on a predicted EQ or a Celebi. Facade hurts. A lot. The only real nag I have is that both Swellow/Lapras are SR weak which make it hard for me to bring them in repeatedly so prediction is more important in my case than most teams. It's my late game sweeper, I guess you could say.

Nidoking (M) @ Life Orb
Ability: Poison Point
EVs: 252 Atk/84 Spd/174 SAtk
Naughty nature (+Atk, -SDef)
- Earthquake
- Megahorn
- Ice Beam
- Fire Blast
---
Crushking. It's a lot more effective than I thought it would be when I first read the set. It does 2 hit KO most of its targets. You just have to keep in mind you're killing walls with this, not other sweepers. Most people expect a full physical set still. Weird. Occasionally, I get surprise kills when they switch which is a bonus. Anyway, it does its job well. Would Toxic Spikes work anywhere? Megahorn is really only for Celebi. And the Toxic damage could help Ludicolo's stalling.

Ludicolo (M) @ Leftovers
Ability: Swift Swim
EVs: 252 HP/76 SAtk/180 SDef
Calm nature (+SDef, -Atk)
- Leech Seed
- Protect
- Surf
- Ice Beam
---
Oh man, this guy has a field day with teams not equipped to handle it. Stall Ludicolo has to be one of the funnest sets ever. If I fudged up with Nidoking early, this guy stalls out most walls unless they carry Toxic or Calm Mind. He serves as my kind of pseudo Special Wall. It can take Special hits, but not repeatedly.
Edit: I have a large Lucario/Heracross weakness. I could use some help with that. Also, feel free to bash on any other holes you see.
