Lucario is blessed with exceptional attacking stats and an amazing movepool, however its lackluster speed hold it back to some extent. Swords Dance and Nasty Plot allow for hammering on both ends of the spectrum with moves like Close Combat, Extremespeed, Crunch, Ice Punch, Aura Sphere, Dark Pulse, and Vacuum Wave to sweep foes. A lot of team support is necessary for Lucario to sweep, as numerous Pokemon like Jellicent, Gliscor, and Gyarados stop various sets. In addition, Pokemon like Conkeldurr, Gengar, and many others can check Lucario and prevent a potential sweep. Lucario is best used as a late game sweeper after a clean sweep is availabe.
Like before, it's better to mention common sets in separate sentences as opposed to being bundled in one sentence. Stuff I've mentioned before applies here too, no need to worry about counters, etc
