Thoughts on
atm? This thread hasn't really discussed him in a while outside of my quandary over Sky and The Wall a few pages back. I think it's safe to say this character is not and will never be as good as he was made out to be in the beginning of this game's young meta. The "amazing frame data" meme has died down since people realized that this dude has more moves than just nair and jab. It's certainly not enough to make up for a horrendously laggy grab, bad roll and spot dodge data, a shield with unique properties that can be problematic (such as not being able to shield drop), and a very linear/predictable recovery. He has good smash attacks but his only setups into them are jab and I'm not sure if they're super reliable (?). His matchups against the top tiers are concerning. He loses to both Diddy and Cloud which is a pretty serious roadblock today.
For all of these reasons I think Yoshi will struggle in tournament and can never be above mid tier. However, he does have some stuff for sure. His mobility is pretty stellar, having the 14th fastest run in the game while touting the fastest aerial speed too. These two things used in conjunction with his b-reversible, wave-bounceable and perfect pivotable command grab mean he has some pretty cool movement options on the ground and in the air. Egg toss is a fantastic projectile that can force approaches, aid recovery, and even convert into an up air. His ground game is a solid outside of his pathetic ftilt and normal grab, with dtilt as a spacing option, a nice dash attack, uptilt as a combo starter/anti air, and jab for jab stuff.
Because Yoshi has some fundamentally flawed design choices while also having some really good and unfamiliar options sprinkled throughout his kit, I think he has a niche as a unique kind of counterpick character that we've seen before from Dabuz. Olimar is not a great character and Dabuz himself acknowledges this. However, Olimar is able to work for him because he's uncommon and has some frustrating tools to deal with. I could see Yoshi achieving this too, with people getting frustrated vs eggs, falling for his grab release shenanigans, over-respecting his recovery, and getting caught by egg lay movement mixups.
