Pro-tip #1 - Don't Jump.
Bowser's fortress (UP + B) attacks on frame one. This is common knowledge, you may be thinking, but! What you may not realize is, pressing up on the control stick will often result in unnecessarily JUMPING.
Bowser's jump is (iirc) airborn on frame 9 or 10?? Effectively, if you input a jump using up before pressing B your move will not come out in 1 frame but will instead come out in 10 or 11 frames!!
While this won't often make the hugest of differences it makes trading with up and b infinitely easier, among other things.
