Yo i just wanna say i finally found the BEST way to practice this ****. SURE level 9 and handicap .5 damage reduction works but it still gets to an awkward knock back eventually.
You wanna know how you can go FOREVER? and the punching bag will NEVER move? its quite easy.
(requires 3 controllers)
Step 1: Pick Fox/Falco, Pick Bowser (or preferred punching bag), Pick ICE CLIMBERS!!!!
Step 2: Use the Climbers and Freeze Glitch the Bowser, Now he's STUCK no matter WTF you do to him.
ADDITIONAL NOTE: WHEN I PICKED BOWSER I USED THE TRICK TO SET IT SO THAT HE'S ALWAYS CROUCH CANCELING. I TRIED THIS ON DREAM LAND AT FIRST AND HE KEPT GOING UP AND UP AND UP. Using this CC method though when picking bowser seems to work?? because i'm like 90% sure that even if your freeze glitched you can DI multi hit attacks.
I realize this takes a bit longer to set up, but if you REALLY wanna practice your pressure try it out.
Feed back?
