aMSa is a Yoshi player from Japan. He is a relatively new player in the scene, beginning to smash competitively in February 2013, but has played the game casually since its release, using Yoshi from the very beginning. He quickly gained notoriety for his ability with such a low tiered character, having a fair amount of technical skill and being able to fully utilize and mix-up all of Yoshi's options, backed up by a fantastic comboing ability. aMSa also does not waste Yoshi's special moves, as he is proficient at using edge-cancelled eggs and playing mind games with his Yoshi Bomb camping on the ledge.
Despite only having played seriously for a short amount of time, he quickly became considered the best Yoshi main in the world after his first international appearance at EVO 2013. Astonishingly, he managed to sweep through his pool without losing a set and make it to quarterfinals, while the only other notable Yoshi main at the venue, Vectorman, failed to even make it out. He managed to take a game off of Mew2King in quarterfinals (to the shock of many spectators) and almost made him contemplate throwing the match, before losing 2-1. He continued defeating opponents in the loser's bracket until he reached a final placement of 25th place, losing to DaShizWiz. He later played many other top professionals in friendlies, including Armada, Axe, and Hungrybox, managing to hold his own in each one (most of his matches went to the last stock); perhaps his most notable moment in these matches was when he 4-stocked SilentSpectre, which many other professionals found impossible to do.
