I don't play Glorfindel much, but if I do, I usually pair him with Gimli or Glóin mainly because of his ability, which can always help in control of damage. His stats are quite good, but his threat is too high for what he can do. It's really hard to play both and so most of the time you can't use his full potential. Also he is more playable in scenarios, where the starting threat is not so big deal. But I try to built deck around him, just to find out if he can be better. Interesting artwork. Verdict: 4/5.
Noble. Noldor. Warrior.
Action: Pay 1 resource from Glorfindel's pool to heal 1 damage on any character. (Limit once per round.)

I really don't understand why people hate Lorefindel. He is expensive and bans both other versions of glorfindel, but as a natural match with asfaloth and a very effective direct damage counter, I'd say he's pretty good. Not stellar, mind you, but good.
