I'd suggest dropping Nelya and Nertea and adding another Enquea and Attea. What would you do with Nelya's extra skirmish twilight? If you have a wounded Nazgul, much better to add burdens than twilight IMO. Also, you might consider that you have 6 cards that rely on using or spotting a Nazgul and only 4 Nazgul minions. This will lead to clog or ineffectiveness.
