I see. The only thing we can do... is perhaps shut her down before she can set up her projectiles and baiting techniques? So basically, we don't give Samus a chance to initiate any of her moves or pressuring tactics. If course this isn't 100% efficient, but maybe we should just shut her down through close-range combat because we excel slightly in that area. Playing defensive isn't going to work, Samus can do everything we do, better.
I remember Xyro saying UpB is highly punishable, perhaps a Uair or something can be of essence?
Naw, I just think he's better than people say he is.
