My thoughts on here changed dramatically. At first I did not like her, but then i figured out how to play her in deck without allies, which is something i always wanted to do. So, i enjoyed that very much, although I do feel she is kind of stuck to Glorfindel and have had a hard time putting her into decks without him.
Here is the thread when she was first released, cool to read about peoples reactions and it also follows the evolution of my thoughts on her.

There is also a a lot of discussion at Tales from the Cards on her if your interested.
