This is one of my favorite decks, and I'd even say one of the best I've played (barring Dwarves and Outlands). First of all, it's a Grima deck that features doomed, and also a pretty good ranger deck overall.

The strategy of this deck is simple: play as aggresively as possible. Light of Valinor is essential as usual, but in this deck what really shines is Grima's ability. Being able to play Light of Valinor, Horse-breeder and Asfaloth on the very first round is huge. In fact, since this deck uses mainly 1-2 cost cards, being able to reduce the cost of any card by 1 each round is incredibly helpful. Gandalf is another essential card tot he deck. Again, being able to quest for 7 without exhausting anybody is amazing, and thanks to Aragorn's ability I can reset my threat to a mere 26. Isengard Messenger, a card I had never used before, is actually pretty good, since I'll be using Grima's ability almost every round. Same thing with Keys of Orthanc. The rest of the deck speaks for itself. It's just rangers and traps, but again, Grima's resource discount really make this strategy viable, especially with Henamarth and the incredible Ithilien Lookout and Wingfoot. This deck often has insane action advantage, and even some treachery cancellation. I've even thought of adding a Palantir or two just for thematic purposes, but as it is, this is just a great deck. It destroyed Bloof of Gondor the other day and after a few tries it won Itho Ithilien pretty easily, so at least Ithilien is safe for now. What do you think of it?

Sound exciting. It's just sad that none of the heroes are Ithilien rangers. It's also sad that there are so many awesome decks here that I don't have time to try.

Assuming all the cards that don't have "x#" after them have only 1 copy, I only count 49 cards.

You're right. At this point all the essential cards are covered, and I changed the deck a bit since I posted it (removed the poisoned stakes, for example), so for that missing card you could just add another copy of any card you'd like, or, as I did, add Saruman or Palantir. Come to think of it, Forest Snare might be a good option, since Gríma greatly helps with the cost.
