For mid to late game when the Noble Arms are mostly in the graveyard. Might be okay for others, but I'm not a conservative Noble Knight player. I go all out and get out protected Medrauts/Artorigus Xyzs as soon as I can to not only get a good advantage early, but to retrieve the dumped Noble Arms for an Artorigus afterward. If it gets destroyed, I have Gwalchavad with Gwenhwyfar to make an Artorigus to continue the process. I can see it being used...but it's just too meh for my build. Maybe if Lady of the Lade was renamed to 'Ninianne, Gifter of Noble Arms' or something...
