Faced a very good Yoshi tonight.
Eggs good. Eggs are real good. I got camped out hard at times and I'm usually the one camping people out. Yoshi also edge guards Mega Man quite well with eggs, DAir, NAir, and his quick vertical double jump, which he can use to respond to us recovering high. I'm awful at footstooling, so that's something I need to address especially for this matchup, but regardless, he's difficult to gimp. Challenging his up-B egg toss jumps is where I found the most success (with NAir or BAir)
I thought that matchup was even before, but I'm leaning towards 40-60 or so in Yoshi's favor. Mega Man can't really take advantage of his slow f14 standing grab and his NAir OOS is a strong option at f9 (3 frames startup + 6 get in the air). We camp him out from killing us quite well and live to high %'s due to being safe and him not having a kill throw, which allows us to get some serious rage (thank Dr. Light for backthrow). But he can camp us out quite well with eggs, and he can convert egg hits into more damaging combos.
It's funny, I was just about to write up the 3 matchups from last week... and now I have a whole new perspective on the Yoshi matchup.
