Toon Link is basically Young Link in a WW model. For me, it doesn't matter if he's a clone or not, I'll still main him.
Again, it's stupid how people say that they hate clones: everyone simply loved Falco's Pillar Combo in Melee.
It's also a bit much to say that Sakurai was being lazy. He's made Brawl into one of the most epic games on the Wii console. In Melee, he said clones were an experiment. Experiment for what? Another Smash game: Mario's got Doc's Fair, Pikachu is just Pichu evolved and not emo, Luigi is still a clone somewhat, and Lucas is basically another Ness with different moves. Furthermore, look at the Star Fox series, they all have the same FS, Wolf suspiciously like Fox, and Falco might still be clone. Same goes for Ganon who might end up being like C. Falcon still, whereas most people thought he'd have a sword. Just because there are some characters with similar movesets, doesn't mean it'll be the end of the world.
