I have a Lucario and I was wondering which I should choose here are the stats
Aura Sphere/Drain Punch
Drain Punch since you are running a all physical set with Swords Dance. Plus you have more attack anyways. You could go mixed if you wanted though.
Aura Sphere Brah
Drain punch has 60 base power and only 5 pp. its not that powerful for draining, since when were the absorbing moves powerful.
Aura sphere has 90 base power and infinite accuracy. That's really special since they're usually 60. plus don't you wanna use lucario's so called signature move
