Many Dunedain Decks use Damrod to play their Forest Snares for a lower cost. I believe that this is kind of suboptimal, because other traps (like Ranger Spikes or Poisoned Stakes) don't combine well with the Dunedain Deck.
But there is another hero that can play cheap Forest Snares: Gríma. You lose Damrod's cad draw, but this is thanks to Sarn Ford Sentry not such a big deal. The extra threat is often even beneficial for a Dunedain Deck, and other players shouldn't worry to much about it, because you will take the enemies. And if you get the Keys of Orthanc out, you can basically gain two ressources per round, so you can play your defense attachments and allies much faster.
Grima can also become a decent defender. But Golden Shield and A Burning Brand on him and he will be defending for 4, cancelling all shadow effects.
