Whoa big boys and small girls! No Choice Scarf Lucario? Come now, with Lucario's impressive attacking potential from both sides of the spectrum, it can certainly significantly hurt its opposition. You all know how many options Lucario has for its move set, but I've only tried this set so for now I'll only include what I know works. However if you have tried other stuff, feel free to add comments.

[SET COMMENTS]
<p>This set utilizes Choice Scarf in conjunction with Lucario's large move pool and impressive attacking stats in order to create an effective sweeper. Inner Focus is chosen as the choice of ability over Steadfast due to the fact that Choice Scarf already boosts Lucario's Speed, and additional Speed is almost superfluous. Additionally, Lucario will take a hefty 33.8% damage from an Ambipom's Fake Out, meaning if Lucario was flinched, Ambipom could theoretically switch in and switch out in order to defeat Lucario in almost 3 turns.</p>
<p>Close Combat is chosen over Aura Sphere in order to do more damage to Blissey (90%+) and OHKO Tyranitar. Hidden Power Ice is chosen because Gliscor, Garchomp, Hippowdon and Salamence will often switch into Lucario. Dark Pulse is preferred over Shadow Ball for its ability to potentially flinch the opponent, a valuable characteristic when facing Special Defensive Cresselia or Celebi. Finally, Stone Edge was chosen in order to deal damage to Zapdos and Gyarados, especially on the switch. Stone Edge has the potential to 2HKO standard defensive versions of both assuming the omnipresent Sandstorm and Stealth Rock are in play.</p>
<p>The EVs are designed to allow Lucario to always outspeed Choice Scarf Heatran (another common switch into Lucario due to Choice Scarf Heatran's resistance to both Bullet Punch and Extremespeed) and Adamant Dragonite and Gyarados after a Dragon Dance. Emphasis is placed in Special Attack over Attack because the main Pokemon hit by Close Combat, Blissey and Tyranitar, are dealt huge damage and the main Pokemon hit by Stone Edge, Zapdos and Gyarados, are usually 2HKOed provided Sandstorm and Stealth Rock are in play. 352 Special Attack allows Lucario to OHKO 4 HP / 0 SpD Garchomp with Hidden Power Ice most of the time and it allows Lucario to always 2HKO standard 252 HP / 4 SpD Celebi with Dark Pulse provided Stealth Rock is in play.</p>
