I see where you're coming from - Imma give it a try.Wizard's Assault, despite its flaws, goes the furthest distance by a considerable margin, almost 3/4's of FD. As a result, it can take you really far offstage for some incredibly deadly edgeguarding. It's useless by itself though, since the only way to set that up is to land an F-tilt right next to the ledge.
Flame Chain however, sets up for this perfectly. It has horizontal knockback and will drag the opponent to the ledge with no trouble at all. On top of that, you can use Flame Chain to block the ledge for a good 60 frames or so by holding down to avoid grabbing it. It might make a Ganondorf an edgeguarding monster, even better than Pikachu. I haven't tested it a lot yet though, so whether it's worth giving up Choke and Wizkick remains to be seen.
