Think about it. First of all, Master Hand functions horribly on any stage with platforms, which is pretty much all of them. Second, Master Hand telegraphs his (mostly fixed-trajectory) attacks an hour in advance, and is then forced to just sit still for some number of seconds before he can do another one. Thirdly, Master Hand has a huge hurtbox and probably pretty small hitboxes. Playing Master Hand is like playing giant Ganondorf and attempting to win by: Walk stealthily up to opponent -> attempt to utilt opponent -> if miss, stand still for a few seconds until they forget you're there again -> walk stealthily up to opponent, etc.
