I just bred a 6IV Hasty Riolu that knows Vacuum Wave and Bullet Punch. What would be two good moves to give it.
Psychic and Crunch provide good coverage for a mixed Lucario.
Try flash cannon and close combat. You'll get 2x every time you attack. Plus good power. Hope I helped!
Psychic because of the the fighting weakness and aura sphere because it gets STAB and never misses. hope I helped.
