Yup, but I don't think it will last in Expanded, haha. There are some mean fish in the sea there. No sorry, in general beatdown decks don't last too long, in my experience. Most nasty fellowships in standard try to get done before skirmish due to nastyness in maneuver of archery, try denial with Ringbound Hobbits or play as many tricks as you can with Gandalf. You need conditions management, something to get rid of burdens and preferably do some healing as well.
Your deck has the denial part, which is nice, so consider
Merry Swordthain, to get those helmets back.
