I have had a great success in my hobbit decks with this card, it is awesome cuz there are a surprising amount of uses for it. The most common use for it is with Merry because it lets you choose whether you want to quest with hum or use his ability to lower your threat. It lets you choose after encounter cards have been revealed so you know if you need the or not. The lesser known use is with Elevenses to put the attached hero back into the quest after using Elevenses on that hero, it lets you not give up that character's to use this card.
Also, Elevenses works great with Rosie Cotton with a Fast Hitch and Elevenses because she will never lose her willpower!
