DH is very complicated and not really easy to play. There are many deck types, but DH is at its best in TS. It's strong in Movie, too (
Star-glass,
GEW,
Narrow Escape). It can even survive Corsairs, but it's very hard.
Usually, DH is played with direct damage. Some tend to use Double Shots,
PATHS,
Gondor Bowmen, Splendor and
Aragorn's Bow. Too much exerting for my taste. Sure those decks have
King in Exile,
HTGG and
Galadriel LOTGW, but it's still not enough healing for those kind of exertions. Besides,
Aragorn's Bow and
Gondor Bowmen cancel each other out IMO. Also, it tends to lose very badly against Sauron Grind or any other kind of direct wounding. Also to
Relentless Charge. And with every archery based freeps, if anything comes through to skirmish, you're most likely toast. Not to mention the major drawbacks of facing
Isengard Warrior,
Broad-bladed Sword, high vitality wargs,
Easterling Polearm etc.
I like a well balanced approach of direct wounding paired with
Wingfoot. You choke enough to face only a few minions that can be either fought or if necessary bown away by archery.
A Promise deck is strong, too, especially against Dunland with Stealth events hindering Dunland to score their needed win for site control. Or hindering Wargs to simply overwhelm you. Doubling is hard with this freeps.
Your shadow is very important, too. It needs to cycle enough for you to got your freeps cards in hand. Quickly. You want to play Elrond in turn one, for instance. From site 5 on, you should probably just discard him if you don't need him badly.
If you'd like to know anything else, shoot.
