Mindgames are very situation dependent. Starting a "mindgames" thread with no specific situation or context go off of doesn't usually make for a good thread.
Maybe if you could provide a mindgame situation that you could be thinking of with Ganon, then by all means, go ahead and share it!
I was thinking individuals would bring up certain situations and mindgames they use, for example a ganon main I know will sometimes charge an upsmash in neutral and then jab directly after it when a player tries to punish it.
A mindgame I use sometimes is sticky walking out of a waveland away and then dash attacking out of the sticky walk, it catches a lot of people off guard
Maybe these aren't exactly mindgames? More like tricks or mixups? Sorry I'm relatively new to smash (I joined around the time sm4sh came out) and am just trying to get involved with the community more.
