yeah, distance and timming is the key, the exact distance to deny DD from taking out hes 2nd banana, also making hes glide toss less usable at short mid range (cuz if u dodge the banana just pass u over), sweet spot F smash, and my favorite move, shuter step back F smash, also if u call right nayru the banana reflection hit DD (if u are at mid long distance u reflect but the banana doesnt hit DD).
the advantage of shuter step back plus F smash its awesome in Zelda case, cuz her fox trot its short and quick plus in the first frames of F smash she pull back, then attack, if u learn how to timming right, u dodge and attack at the same time. against MK, Snake works beautiful, dodging the grab and attacking. in DD case, u have to use it when he doesnt have a banana. xD
