This topic is about G&W.

G&W's uair causes a gust upwards, so if neither attack hits, there is still and upward force.
G&W's upb causes a trampoline to appear, if others are going by it and they dont get hit by you, they can use it, but it doesnt last long at all.
G&W's dair is a spike, only at the beginning. it isnt a good thing to kill via spike, but it can carry a foe down to get his with the landing.
G&W's bair has multiple hits and pokes through shields pretty well. RAR to approach with great ease.
