Well, if you think about it, it's a better idea to go with a character that isn't Link. Compared to the action of real swordfights, doing the same thing in a turn-based fashion isn't that fun. But Tingle will likely fight (or combat, or duel, or whatever you want to call it) in a completely different way, thus it's a bit more appealing, since it'll likely be fun in a creative sense.
Plus, you know it's going to be funny, and there's a sore lack of good, funny games.
