Ok, so last night I stayed up building a team that was to be better than my last two. But it still has issues. It is built around the idea of setting up Lucario's sweep, and It can work, but it tends to lose against well-built teams. I think this may be due to an offensive imbalance, but judge for yourself. Pokemon and move changes are welcome suggestions. And be constructive, please! All advice is good advice!

Awesome lead, as you know. Counters Gyra leads, many fast sweeper leads (Aero, Crobat, ect) and sleeps everything else. Also blocks Rapid Spinners later in the game.
Lucario@ Life Orb

Close Combat
Extremspeed
Swords Dance
Crunch
SD Luke. Can sweep like a beast when set up. The goal is to have him come out and kill, kill, kill after the foes team is weakened by t-wave, sleep, stralth rock, item loss. (Bullet punch < Crunch? I wanted Crunch for pokes like Cress and Celebi, that my team has a hard time countering otherwise)

Special wall for team lacking in special defenses. Ya, I know, Ice beam over S-toss, but I've been walled by bulky waters (mainly cune) when S-toss would have helped me strike back. Meshes well with Stealth Rocks by forcing swithces, and cleans team of status effects that quite frankly, SUCK.

Physical wall who provides some support with knock off, covers weaknesses, and counters some of the metagames worst threats ( mainly Hera and SD Lucario)

Rapid spinner, mostly... meh, T-bolt over ice beam for Gyra, as this team dosen't really have that much trouble with dragons. Now that I think about she does little but spin and could easily be replaced.

Stealth Rocks is needed on this team, and he also provides solid pyhsical defenses, as well as being a failry heavy hitter. Could also be replaced, but I found he works pretty well.
