Ganondorf
down+B should have been his ground pound from OoT.
Neutral B should have been a lighting ball that sound be reflected by smash attacks.
Up+B should have just been a levitating move, where he could float around however he wanted for a few seconds with the ability to do any of his normal aerial moves and his neutral B but after the time is up he would go into a flashing fall so he couldn't do anything else (you could end the levitation early by pressing a shield button or activating a down+B or forward+B from it)... note that he won't be able to change which direction he is facing by pressing left or right during this.
Forward+B I would keep the same as it was in brawl... too cool.
Normal Changes
Nair: Like his jab on the ground but angled downwards. Has little landing lag and its knockback is pretty much set (barely changes from low to high %s).
Bair: A swift kick back, similar to Falco's but a bit slower and still has the great knockback of his current bair.
F+tilt: Pulls out his sword and swings it like a beamsword from melee. Has a longer follow through though as he has to put his sword away after.
