Extreme Harasser Lucario - PyProd

Guide

This build firstly capitalizes on Lucario offensively supporting other Pokémon by weakening or killing opposing Pokémon. I mainly play it in Bottom Lane, where I fare best, but due to Lucario's sheer versatility, you can also use it in Jungle. However, this guide won't focus on this Lucario build as a Jungler, and you might be better off taking Power-Up Punch or looking at another guide then.

I like Quick Attack as my first pick to have the guarantee of the dash if I ever end up in a pickly situation. Moreover, your early game should just be you getting one or two hits off the wild Aipom to get the shared exp. You'd rather leave this exp to your mate who needs to evolve as soon as possible. Quick Attack should be used so as to hit both last Aipom. You have to be fast enough to be able to fight the Audino on top of the Bottom Lane to deny your opponents its exp.

In the early, using Meteor Mash's knockback to save your mate from pursuers is well appreciated. It can also knock them away from their goals if placed right. You now have to take the Audinos at the bottom of the Lane's shared exp, as well as the bees. You need to unlock Extreme Speed as soon as possible. Extreme Speed allows you to harass early game with its great power, making you capable of 3HKOing most opponents. It also enables you to clear the bees faster once they reappear. You can also use said bees to get two or three dashes if you end up in dire situations. You should bully late-game Pokémon such as Ralts as much as possible. All in all, you aim to soften up the opposing defense for your mates to clear. When the coast is clear, dunk a few points.

Extreme Speed also allows you to be a great defense, as you can take on multiple opposing Pokémon and wear them down quite easily, which can scare them off.

Bone Rush, once unlocked, allows you to further harass opposing team members. You can use it to further pursue an enemy who used an Eject Button to try and get away from you, although you should avoid trying to 1v1 Pokémon in opposing goal zones. In the late-game, you can use Extreme Speed and Bone Rush to soften enemy Pokémon if you want to take or defend Zapdos. Don't worry if you die in the process, you're less valuable than the opposing Attackers and your damage goes a long way.

This build uses the Buddy Barrier so as to be a better support that can be quite good in teamfights, especially since otherwise, Lucario's UNITE move is pretty easy to avoid. The Muscle Band further empowers Lucario, which makes its assaults difficult to escape from for frailer Pokémon, while the Focus Band synergizes well with the Steadfast shield, although you should be wary of its hidden cooldown.

The Full Heal is chosen as your Battle Item to turn would-be hard matchups against opposing Ninetales-Alola and Pikachu in your favor, and proceed to weaken or beat them. You also block Gengar from using Hex repeatedly on you and get away safely. The Eject Button could be used alternatively.
