Good thing to do with ZSS RAR at the oppenent, and fastfall and do back air with the C-stick. <--most of my game.
Also you connect any move shorthop at immediate f-air, and keep holding forward. Not always true, but it works more than you expect.
Never do over B running forward unless you are sure the opponent doesn't expect it, or you are baiting for the 1,2 punch/ projectile countering.
Some combos, shorthop fastfall neutral air, shorthop instant f-air. (can swap out for u-air but its more difficult to hit and doesn't do as much damage).
Finisher D-smash, first 2 jabs, double jump, u-air/back air/ 1-2 punch, depending upon stage and position.
Blatant disrespect: Using your down B to do a invulnerable head tap off of people during their up B. Bowsers/DK love it :D.
