Marth:
-lasers ****, but he likes to do stuff after your laser comes out. switch between attacking directly after the laser and using movement tricks to hit him afterward
-he sucks in his shield unlike peach so **** that
-when he's above you he's pretty useless usually. don't let him fall at a diagonal to you and watch for side Bs. empty hop some to bait that stuff out if you want
-run up shield disrupts his spacing sometime and can get you a free hit
-wavedashes ****(especially into Marth) I promise
-watch zhu vs m2k from no johns last summer to learn how to edgeguard him. dj regrabbing *****
-if he Fthrows you offstage, DI away
that's probly the main stuff lol
