Marth's combo game is great against CF, but nothing trumps CFs combo game on Marth. Pretty much starting from a grab at 0, CF can tech chase/DI read on reaction combo Marth to death. Marth doesn't really "combo" CF from 0-40, and a lot of marth combos are circumstantial/escapable before a KO move is actually delivered. Marth will actually need to make a few reads (aka educated guesses) in order to combo CF fully through to death, but CF actually doesn't even need this. He can defeat Marth on reaction alone (after finding an initial opening, of course). Obviously the CF needs to be fantastic to execute flawlessly like that over and over again but the great CFs do it.
