I have been using this team to success on the ladder so far, but proper support and certain pokes should be eliminated before sending him out. When he is sent out he will gain some surprise kills here and there. Besides Lucario is not seen as often in todays metagame, i don't know why, but Lucario is a beast regardless of what set you use.

[SET COMMENTS]
<p>By either using a physical move or a special move first, your opponent will assume either a physical set or a special set. Close Combat is there for STAB and to pick off slow non-choiced scarfed pokes(ie: T-Tar, Heatran). Vacuum Wave is for a STAB priority and allows you to pick off weakend pokes as well as take out scarftar and scarftran. The choice between ice punch and stone edge is up to what you want to hit. Ice punch lets you hit gliscor and non scarfed flygon for super effective damage, but note: ice punch will only do around 30% to hippowdon. Stone Edge hits Gyara hard on the switch, but the less PP and lower accuracy makes it a bit less reliable. Dark pulse hits rotom-a harder than crunch because most rotom-a invest more in Def then in SpD, but if you still want crunch thats also usuable.</p>
<p>The choice of item depends on what set you want to bluff. An expert belt lets you bluff the choice specs set, but the LO lets you bluff the more populat SD set. Nontheless Lucario is not the bulkiest of sweepers, so wish support is greatly appreciated. Vapoeron is the best partner on this set, because of its acces to wish and resisting fire/ground atks aimed at Lucario. Suicune is a lesser choice, but its still usuable, although the lack of wish makes Lucario even easier to take down.</p>
<p>The Ev's given allow you to hit 289Atk which is enough to OHKO blissey and tyranitar. The Ev's and the nature let you hit 306Spe outspeeding the standard stall breaker gliscor and letting you hit back with SE ice punch. The Ev's also let you hit 297SpA a gurantee a OHKO on scarftar and scarftran.</p>

<p>Aura Sphere is not used in this set because of the lack of SpA investment and the lost of a Specs. makes it weaker, so Close combat is a better choice. Extreme is a lesser option to take down Gyara, but scarftran and scarftar will run through set. Like all Lucario sets entry hazourds are always nice. As mentioned Vappy is a great partner for Lucario because of its wish support and resists to SE moves against Lucario. A great offensive partner for Lucario is Salamence because of the great synergy they have. A more defensive partner for Lucario is swapert, who switches in on scarftar with ease and same thing applies to scarftran as long as it doesn't have hp grass. The biggest counter to this set is Infernape, who can survive all the your moves and hit back with SE fire blast/flame thrower. Another big counter is Bronzong and swampert who can both survive your attacks and OHKO back. As mentioned the team should be used to support Lucario and remove Lucario of it's biggest counters</p>
*Sorry if it was a bit short, but I'm tired*
