Spamming aura sphere against characters that can use it against you is my favorite mindgame...especially against Ness and Lucas. They want to absorb it, but I spam it when I know it won't hit, when they do not have time to down B, or when it will hit. It can frustrate them. Then they try and predict it, so I can punish their down B. With Fox/Falco/Wolf, I like to SH aura sphere a few times, then they expect another SH aura sphere, so they hit down B and I take advantage. Against G&W it's tougher, becase the bucket is so deadly, but I still do it vs. G&W.
