Not bad. I think Mario's attacks should be exactly how they were in melee but buffed. His neutral b can be repeatedly pressed for 3 rapid fireballs fired from both hands. His side b can be held in midair to assist him in a gliding recovery like Metaknight but to balance it, you can only do this or sjp. This means you can midair jump and glide to recover from above the stage or midair jump and sjp to recover from below the stage. This ability can only be activated from the first cape in midair because if you could activate it whenever you wanted it would be broken. Mario would knockback an opponent off the stage then proceed to chase them by double jumping away from the stage to cape them(seriously gimping their recovery), all while gliding back to safety. His down b should be the Luma spin. It should be a one hit attack with good knockback and a little ascension, like in the galaxy games, for vertical recovery. In galaxy you can do them in quick succession for a max of 2 or 3 hits, i dont remember, each one ascending. That should be implemented in ssb4. His up b should stay the same. Maybe it should be given a little more knockback and invincibility.
