Galadriel's ring, Mithril coat and Sting, and possibly other cards allow the FP to draw an additional Hunt tile if they don't like the one already drawn. "We shall get it" allows the SP to do the same thing. In what order are these items played?
Nenya may be used immediately if the draw is an Eye. "We Shall Get It" may then be used, whether or not Nenya was. Then, "Mithril Coat and Sting" may be used, regardless of whether or not Nenya and/or "We Shall Get It" was used. Also, Nenya may be used (if it hasn't been already) after either "We Shall Get It" or "Mithril Coat and Sting" if an Eye is drawn.
