Y'know, if Ganondorf had to be a clone, Ike would probably make the most sense. Heavy sword user with really powerful attacks. Just swap out the aether animation with some kind of dark energy thing, and change quick draw to an animation of TP pig-ganon dashing.
I wouldn't want that at all. If Ganondorf has to be a clone I think he's the best as he is.
If anything, the problem isn't that Ganondorf isn't using a sword in Smash, it's that he's not punching the shit out of things in Zelda games. I love how he FEELS in Brawl, he's like a Fist Wizard. He sucks, sure, but he feels satisfying to play as. I would like to see him get a moveset revamp but I would want them to keep how hefty and brutal he feels in Brawl.
