I'm considering whether to include this in my deck or not. Attached to a powerful hero it can certainly make a difference.
But I don't suppose it combos with Boromir's or Caldara's ability? The wording on the heroes are, I think, "discard" while FoGG requires the hero to be "destroyed" - not generally "leave play". Otherwise it would be a very powerful combo with Boromir - dealing 2 damage to multiple enemies and then lowering your threat by 11.
I'm not sure it's worth building around, to me, but one strategy could be to attach it to a hero of a high-threat player if you have Landroval or Fortune or Fate available. Elrond would be the most effective, if you don't already have several attachments or resources on him.
