Abuse Extreme Speed Lucario - elpakito

Guide

This build works extremly well with pokemons that can set you up, such as eldegoss, mamoswine, wigglytuff, mrmime with his wall.

How you want to play:

Early Game:
Use Quick Attack into meteor Mash on Audino / corphish and displace them into your team to secure early objective, into enemys play with the same method, dash into them and try to push them in your team direction, if your are struggling to fight you can also play defensive and use meteor mash to peel away.
Once you get Extreme Speed it becomes so much easier, on vespiqueen you want to Extreme Speed in and get them all with your multiple Resets, remember that the resets work for individual enemy mons or monsters.

Mid Game:
This is where the fun begins, when the map is a little bit more open, close fights at Drednaw is the perfect spot for this kind of lucario, you can easily chase down low hp enemys perma jumping on monsters or another enemy mon getting the kill and ejecting button out, Remember if you can fast kill one of the enemys fast enough your team should have the upper hand in the fights.

Late Game:
Lucario falls off late game it gets outscaled by Cinderace, Gardevoir, you can still kill them if you get close enough but their dmg and range are really high so you gotta watch out try to go for the weak mons and avoid fighting tanks, at this stage is almost imposible for you to solo them.
If enemys are distracted try to go for sneaky scores, if they chase you with bone rush you can reset your Extreme Speed cool down teleporting back, outsmarting your enemy with some resets will grant your team time for scoring themselves or getting time for zaptos.

Scoring/Items:
Since we run Attack Weight you want to score as much as possible early to mid game, doesnt really matter how much points since the dmg amp is always the same,
Late game is preatty hard to score since it requires so much time, you can still try to score and out smart your enemies as mentioned above.
You can also run Goal-Getter instead of Eject Button since you already have a lot of mobility or if you want to run Eject Button you can change the Muscle Band for Score Shield which would give you this extra shield.

Score shield over Muscle Band:
By running Score shield over Muscle Band you will lose some early to mid dmg but you can compensate with scoring more which would grant you more and more damage thanks to the Attack Weight, it is a matter of preferences and games sometimes you run one kind of set up and it is not as efficient as you would like and other times it is.

Razor Claw sinergizes very well with Attack weight, since lucario is melee it also slows.

Unite movement:
Try to use it for damage when you are fighting grupped people or to steal objectives (Zaptos, Rotom, Drednaw)
