How about Link? Hes the least campy of the three. Has great spacing with sword. Projectiles to break the space and deal with spammers. Remote bombs for set ups and stage control. He's got some of, if not THE, best edgeguarding in the game. Great recovery + heavy weight. One of the fastest grabs in the game + d-throw combos at early percents. Just about everything is a kill move, including bombs!
Only thing is, I would argue that he's tougher to learn than some. But once you get the trapping down, the rest of it comes together.
Either that or I would say Pikachu. Hes fast, has a good projectile and has good combo set-ups. I would say he's highly adaptable to each fight. Only thing is he's light, so a big hit can send him out early.
