How much of a clone would she be? The same as toon link is to link? I mean, maybe the MAIN reason zelda has the phantom slash as her down B is because it's toon zelda's move, and they're basically clones of each other in the same way that link/toon link are clones. Different normals, similar specials (that behave differently).
Maybe she uses the torch phantom from spirit tracks
Maybe din's fire works like it does in project M or becomes a trap, similar to snake's landmine or C4 (but highly visible).
