"I'm having a hell of a time vs Marth's. Can I have some advice? I know the basics...
Never jab-> F-tilt just F-tilt (or you'll eat an Up-B)
Don't try to grab off of F-airs or you'll eat a tipped F-smash
Dash attack works wonders
Grenades grenades grenades
Try to read his dancing blade mixups
You're screwed on the ledge.
I still seem to get eaten by Marth's though.. halp!"
Saw this on Kenny's page, you've got a lot of it right BUT one thing you're missing is:
DI out of dancing blade > punish !
If he usmashes, you can double stick it down. quarter circle DI your control stick down and then mash down on the c-stick repeatedly.
You'll be beating the ultimate saiyan in no time
Don't be afraid to trade hits with his fair by using bair either, he dies earlier than you do ;D
Don't get gimped!!!
