I'm wondering exactly how crouch canceling works. If you're on the ground, holding the stick down, will you automatically crouch cancel anything that hits you? Or does it only work some of the time? Also, is there crouch canceling or something like it in the air? I vaguely remember a Fox/Luigi match where I hit my friend in the air with Luigi's upB at high enough percentage to kill, but he barely went off the top of the screen. I could be remembering that wrong, though. Lastly, is crouch canceling even worth bothering with? I've seen crouch canceling (at least, I think it's crouch canceling) dramatically reduce the sending power of upsmashes and stuff, but I rarely see anyone actually do it.
