Not only Lucario 4x resists Rock Arceus's STAB, it also packs a super effective STAB Close Combat to strike back hard and possibly OHKO it! Lucario also has a way to boost its Attack further by using Swords Dance, which after a single Swords Dance it skyrockets Lucario's Attack to a whooping 700 stat. After a single Swords Dance, even Groudon falls for Lucario, as it takes over 65% from Close Combat. Lucario also gets an amazing priority move in ExtremeSpeed which is very reliable. After a Justified boost, Darkrai takes over 64% from ExtremeSpeed as well, making it a viable switch-in. Lucario can also defeat Dark Arceus with no Focus Blast with that ability. Shadow Claw rounds up the set with coverage, allowing Lucario to hit Lugia and Giratina formes for super effective damage.
Lucario really appreciates entry hazards, especially Spikes. Thus, either Ferrothorn, Forretress, or Skarmory are great partners, as all can lay down Spikes. The EVs give Lucario maximum offensive power, allowing it to hit as hard and as fast as possible. Jolly nature can be used to outspeed more Pokemon, but that's redudant because Lucario really appreciates the extra attack from Adamant. Life Orb grants more power to Lucario by increasing the damage output, while still retaining the ability to change moves, all in the cost of 10% of Lucario's health per attack.
