Hey, I can K.O. a Yoshi, and did. And forming a plan to beat Peach is kinda easy with Falco/Pikachu.
As for that second part, all I'm hearing is "wah wah", because Egg-Spamming and EggRoll Spamming is no different from any other spamming, whether it be my trusty Blaster, Mario's Cape or FireBalls, Marth Counter, etc.; part of the character's moveset, and perfectly justified.
(Then we get into Chainthrows and the like, which aren't. You'll notice I throw, but never Chainthrow.)
I forgot how fun Sudden Death matches were, though.
Tense, a decent test of skill, and even if ya lose, it's so frantic, it fairly well levels the playing field.
