Which of these Lucario should I keep/is best to keep in a team?

I have 3 Lucario, all of them are level 100, but they have different natures and slightly different movesets(before anyone flags: Should I ask this at the Battle Subway?):

Lucario #1 (Gaia)@ Black BeltNature: MildAura SphereDragon PulseDark PulseStrength

Lucario #2 (Anubis) @LucarioniteNature: SeriousAura SphereSwords DanceClose CombatFlash Cannon

Lucario #3Nature: JollyAura SphereDragon PulseFocus BlastExtremespeed

Are there any other details I should add? I don’t know how to calculate EVs/IVs…

The one I use the most is Lucario #1, but I don’t really relish the fact that he has a Mild Nature. My least favorite to use is Lucario #2 because I know I can improve its moveset (unless you think it’s fine for an in-game set, at least.) Lucario #3 seems all right to me but I barely use it. I know all of their movesets have some similarities, so perhaps this is just a “battle of the natures”? Thanks in advance!!

You shouldn’t go for any of them, they are all mediocre sets with only slightly decent natures. The only one considered good is Adamant, but Lucario can rely on Swords Dance and Nasty Plot, so just look for a speed boosting nature, either Timid or Jolly, and go with either the Nasty Plot or Swords Dance set depending on your team’s needs/nature.
