ganon has to carve out space on the ground. even though his aerials are primarily the moves that can't be challenged, he can take space on the ground because his CC is so strong. if the opponent fears you taking space by your aerials, taking it on foot can surprise the opponent in a way that could prove...useful.
dash dance can give up space in a way that allows you to counter, but using it offensively is odd unless you're pressuring someone in a corner, from my experience. i think up angled ftilt needs to be explored a little more, as even though its timing is precise, it's ability to cause knockdown at lower percents seems pretty good.
