I've played against Akashi with Kirby in brackets, I remember. I also specifically remember playing my first matches ever against him in friendlies, him using Marth first and me Kirby, and I won. Then he switched to Snake and hogged the TV two rounds, and I won both anyway.
It also happened to me a week or two ago on base playing Melee with a very nice player, man those moments are why I love Smash.
But yeah, I've used ZSS to mix things up and keep her warmed up. I double main both of em, if I suck with one of them and I'm against a character that's better for the one I've been using all day, I'm ****ed! Last tourney that I went to (which was also my second, sad for me), I went mostly ZSS instead of Kirby the entire tourney and used Kirby as a backup, so maybe you remember that one? Cuz my first tourney I went majority Kirby and only instance I remember using ZSS is against Arty's ICs in pools (which I won but then people say his ICs suck so I'm like
) and maybe a match or two in brackets.
