The thing about the Zelda Series, though, is that there are two styles: Realistic console games, and cartoony handheld(Sometimes console) games.
Zelda only has a few characters, but it's practically two games in one.
As such, I think repping both halves of the Zelda franchise is important, even if it's just "toon vs realistic" of the same few characters.
Toon Zelda + Tetra for smash 4! Tetra can fill the Brawl hole of my beloved Young Link..
Yeah, I think either cut T Link or add Tetra and/or T Zelda.
