I haven't seen anything about this in the ganon guides so this is probably new. His Up-B has better grab range than his regular grab but on opponents about Mario's height or taller there is a trick to getting more range than an f-tilt. Do a short hop, up-b as soon as possible, and DI diagonally downwards towards the opponent (during the up-B not jumping to your opponent then up-bing). It looks kinda funky and very intimidating. It probably isn't too useful but it is an unexpected option for punishing shield spammers.
