Book is good enough for me to keep, I do not own a
Aragorn, RotN, otherwise I'd use him. I like Legolas as general protection, if I were to take him out, he wouldn't be replaced. Grima is no problem. I could add
Baruk Khazad if I needed, or like you suggested Preperations with
Slaked thirsts. But this is a RL deck, and no one I play owns a Grima Wormtounge. If I played GCCG, I would add that, but The GCCG is broken for me right now.
As for forces, yes. So I suppose this should be open.
