I hate it when my boi is so good in Smash and STILL no global competitor will use him in tourneys...
Also, before I forget...not sure how Yoshi does in 64/Original tournaments. So I'm ignorant there. Would have to do more research. But in general...
: Amsa; good tournament results but mediocre theory. Solid mid-tier, upper half of mid-tier actually. Would be a high tier if his moveset and weaknesses weren't volatile. Either way, Melee Yoshi (and Amsa) shouldn't be slept on considering how his meta has progressed father than ever expected.
No pro player that's at top level; slightly better theory that's still average but worse tournament results. Borderline low tier.
Debate-ably, Raptor...although Raptor fell off once DLC took over the meta. Good theory, poor tournament results. VERY middle tier.
No solid top player atm, will have to let the meta develop more. Similar to Smash 4...good theory, but poor tournament results so far. If this trajectory continues, he'll fall to mid tier eventually.
PM Yoshi is his saddest incarnation. I feel bad for PM Yoshi, tbh.
