>>45061703I'd ditch Vacuum Wave for Aura Sphere, Force Palm for Copycat, Double Team for Bone Rush, and Reversal for Meteor Mash. Its just to help Lucario be the best close range fighter they can while also giving them a large set of coverage and options.
Copycat is one of the most broken moves imo in the anime universe. The ability to wait for a foe to make an attack and steal their move for yourself while also having the creativity that ash has would be crazy strong. Not to mention its potential in doubles/Raid Battles where he could copycat a move from one of his allies. Copycat Electroweb, Blazekicks, or Anything really.
