OK, my ratings aren't always the best, but I hope my humble opinion with help improve your team.
Excellent, excellent. My only suggestion is Seismic Toss for the attacking move(will do good, Substitute ruining damage at LV 100), but Charge Beam would work too.
Jolly Nature lowers Special Attack, so either change the Nature or the set. I suspect you may not want to switch your Lucario for another, so I'll give you a physical set, but if you are willing, exchange it for a Timid or Modest Nature Lucario.
Lucario @ Choice Band/Life Orb
Adamant Nature/Jolly Nature
Close Combat/Shadow Claw
As you can see, I left a lot open for your personal preferences.
Nothing to add here except that you should consider Rest+Chesto Berry. Leftovers.
Go Swords Dance or Hone Claws, not both, as Absol has trouble setting up before being KO'd. Try this:
Absol @ Focus Sash
The last move is your choice, but personally I would go with Superpower. Pursuit can be great in the right situation, though. I think 1 Dark Type move is enough, so Night Slash is only a suggestion because of the Super Luck Ability.
Looking great, but use Air Slash instead of Fly(Special Move instead of Physical), and consider Roost. (I would just give it Air Slash and leave it at that.)
Expert Belt item.
I noticed a Fighting weakness. Last Pokemon should be..
Mismagius @ Choice Specs
Timid Nature/Modest Nature
Hidden Power Fighting
Yeah, this set is basically from Smogon, but with Energy Ball. I'd go with Modest Nature.
Good luck, and don't forget to have fun!
