How is it Trash? You literally get a double jump, then down +b and another single jump. Or do you not know how to play Ganon, OH WAIT, you don't. His sweet spot is tough, but you can not only doing it facing forward, but also reverse up+b and still sweet it.
Reverse uair can kill at 25-30%, continually reverse uair with the tip of the foot, and they get pushed back far enough off the edge, and they can't sweet spot it, either, if you time your r-uair correctly. Sorry, wrong again.
Stay near the middle? Yeah, if you want to get CG'd, or SHDL, or needled or turniped to death. Yes, you can Power Shield all of that, or avoid via jumping/dbl jumping, but the lag will allow the enemy to close in, and Ganon has NO spam moves. You can CG fasties until about thirty, then maybe a uthrow to a uair, shffld, uair, ftilt of stage, then it's time to edge guard.
If you're going to play Smash, at least know how to play Smash. You're a douche. You blow.
Sincerely, a guy who isn't dumb as **** and has played for more than 5 minutes and knows what advanced techs are. Oh yeah, try wavelanding with Ganon on Dreamland or FoD, and tell me how terrible he is.
