Marth takes a mental drain on the user, but it honestly didn't seem like he was tired to me. Rather just a difference in the ability to be consistent with his character at an ~equal level in skill and Marth's other flaws. Last time he played Masha that I knew of it came down to last hit and he barely won. This time after even more experience off wifi Masha won in a last hit situation. And considering he had already played Masha in the past there was much less to actually adapt to or rather it was more a Masha had already adapted to Mikeneko's near perfect Marth. He's also probably played SLS at some point in the past at least once so I would say matchup experience isn't the issue with Falco (and he had played Salem, quK, and Kamemushi's ZSSes ----and now Saskaska's).I agree. Mikeneko is just an exceptional user of marth, but falco has more potential and excels in many different areas.
Also, I think Mikeneko was either not used to these match-ups or was quite tired, since I didn't see him adapt as quick as he did at apex.
