I hope you meant U-Air. Up-B is good at finishing.8. Luigi: Very floaty, medium light, down air is a drill, can tap a against a shield into a throw, up b is very good at comboing, moderately bad projectile, down b can kill as well, moderately difficult to combo
Also, when used on the ground, Down-B doesn't send you speeding forward like it does in Melee/Brawl. You stay in one spot.
I'd also suggest that Link's U-Smash hitbox be altered. IIRC it's three HUGE sweeps in Brawl, which, if present in 64, would make Link different (knowing when to U-Smash is important, as punishing a missed U-Smash is tremendously easy). It'd be like 3x U-Tilt, and U-Tilt is already a very, very good combo technique in 64.
