This is a silly challenge idea that I started doing in Shadow Dragon since a bunch of the characters, including many of the best (Jagen, Caeda, Minerva, Barst, Lena, etc.), have an A in their name, and we rarely see FE runs with silly restrictions like this. It's been a lot of fun because it forces you to use some trash characters (Bord, Roger, Dolph) with just enough good ones (Merric, Wendell, Tiki) to keep you sane. My only problem is that it has to be played on Normal mode since, without Frey, Gordin (and I don't want to shock anyone with this) cannot solo Chapter 1, at least with any strategy I could formulate. I also couldn't figure out a way to beat Chapter 1 with just Gordin and Norne. To make the challenge harder since normal mode is mostly a cakewalk, I reclass Frey into an Archer in Chapter 5 and then bench him later.
I would definitely be interested if anyone has a strategy to beat Chapter 1 with just Gordin on a hard difficulty while also being fast enough to kill the thief before he reaches Wrys' village.
