Get good at dodging projectiles and such. Most people dont dodge and the either expect their attack to hit/miss/shield. So dodging a projectile in the air throws people off a bit because you can still move around while doing it.
Best practice for this is fight pit or rob and only have them use projectiles.
Also keep in mind that Marth can counter almost -anything-. Some of the "longer" attacks, like R.O.B.'s laser beam or Falco's blaster may hit you with the tail end (you'll deflect about half of it before you stop being invincible, at which time you'll get hit with the end of it).
Some things you can counter:
Effectively any projectile.
Hammers and Spazhammers. (Time this right, since the timer counts down on people who are knocked down, and a well-timed counter sure as hell will knock down a hammer-user).
Learn to abuse the ground dodge. Shield and then just tap down gently. Also, abuse your rolls. Nothing is more frustrating than being unable to hit you because you're either dodging or shielded.
Facing:
Dancing Blade's first attack will always face you in whichever direction you use it. In Melee, I used to use the first level of it just to face, and then charge up a b slash. Since it's changed (and I don't really use Marth anymore in Brawl, I prefer Ike), I don't really know how viable it is anymore to do so, but using it to face yourself in a particular direction is always helpful.
