I would say keep all the special moves he has in Melee (for other moves I have to start up the game again, to see how they worked again).

Shadow Ball is quite different from Aura Ball (and Water Shuriken) it travels much faster and "bounces" when he sends it. It may be similar in some way but works different in another way. The rest of his moves are fine, I do agree for more range on his down special, but when using that move twice after each other it can be a really powerful attack.

For his Final Smash I would say Mega Mewtwo Y, as it is the most promoted Mega of Mewtwo, similar to why Charizard has his Mega X evolution. But it should work different than the others. Take in mind that I haven't played the 3DS version.

Mega Charizard X: normal moves(?) he does a twister, special move(?) he does a Fire Blast, and endless flight. Mega Lucario: everything buffed up. Mega Mewtwo Y: builds up with each landed attack and at the end releases a Psystrike all over the stage which is more powerful if you have inflicted more damage.
