All these Marth "is possibly not top tier" posts are triggering me...
Marth is not only top tier, but top 5 and even top 3 possibly. MKLeo demonstrated the potential of Marth, and guess what, that potential ran through the likes of ZeRo, Ally, Anti, VoiD, and Larry Lurr. He DEMOLISHED each and every one of them, and guess what? Each of those players have had more experience in international competition and have developed their respective mains far beyond what Leo has done. That man leveled up so much when he stayed with Keitaro's crew. And he isn't done yet. Marth still has so much more potential. I think many of you underestimate what the power distribution on Marth's sword means. By using an array of sourspots and tipper combinations, Marth has a considerably higher capability to string together moves than many other characters.
Leo was the harbinger for Marth mains to unleash their potential. His spacing game and awesome neutral make him a definite top 5.
Marth is definitively better than the likes of Diddy Kong, Shiek, Cloud, Mario, and many more. If all those character were played at a high potential, Marth would still objectively win.
