I'm surprised this card hasn't received any real buzz on this page (although I've seen it appear in quite a few decklists. For me, this is my favorite and in my opinion, one of the best healing options out there. It might stem from the fact that Lore is my least played sphere and I always seem to have at least one leadership hero in most of my lists. It's a free heal the turn it comes out and while it's cost efficiency does eventually lose to cards like Ioreth or Warden of Healing the payments aren't dedicated to particular player or resource which is nice.
If Elrond is out then obviously this gets even sillier. My experience has shown me that this card can really clean up archery damage. Not to reference the two allies above but another plus for this card versus the allies is that it doesn't require any exhausting to trigger, meaning you have more than just one shot at the healing.
Not much more to say about this card. I think enough people have seen its versatility and just how much it can save Heroes. I guess a downside is you can't heal allies with this, but that's a pretty minor negative depending on the decklist.
