Sorry DeadlyScyther, but iSharingan is right, please be able to handle criticism from other members, after all, as long as it's good criticism, it's advice. The set is very niche and doesn't really offer much except for Lucario's assured death, as Lucario isn't bulky enough to really use Follow Me, and with the influx of Kyogre and Groudon, both of which having signature moves that hit both of your Pokemon, makes Follow Me only situational. Adding onto that, most Xerneas use Dazzling Gleam, and Mega Khan will probably be trying to take Lucario out anyways, which it will most likely successfully do. Smeargle has Dark Void, which will put both of your Pokemon to sleep, Mega Salamence can carry Hyper Voice, which will be Flying and hit both Pokemon as well, and if Salamence was sent out before it Mega Evolved, well, you're at -1 Atk. I'm only listing some of the most common Pokemon encountered in VGC, and I haven't even mentioned Mega Rayquaza yet, which is also one of the biggest threats in doubles.
Listen, it's great that you want to come up with your own movesets, I'm the same way, custom sets are great
but, this set is defeated by the most commonly encountered Pokemon that you'll be facing in doubles. However, iSharingan is not only a tutor, but experienced with making custom movesets, probably even the most experienced on site! He can definitely help improve your ability to create custom movesets if that is your goal.
If you're firm on the set than all I can do is recommend using Helping Hand over Roar and perhaps Drain Punch or Mach Punch over Super Power, albeit I think offensive Lucario is better, and even then there is a better Pokemon in doubles that can fulfill the same role; Togekiss, which also gets Tailwind, Roost, Air Slash, Thunder Wave, and Fire Blast.
Lastly, please edit the moveset you posted and any future movesets in this format:
Lucario @ Item
Nature
EVs
IVS (if in-game)
- Move 1
- Move 2
- Move 3
- Move 4
And explain why you chose the moves your Pokemon has, what they do, and what it is your wanting the set overall to do, if you have any questions, feel free to ask any of us
