Here is a new deck I built that uses ranger traps and direct damage to neutralize enemies. The hero lineup is Argalad, Thurindir, and Damrod. Thurindir is there so that Legacy Blade can be boosted by an early Gather Information so that Aragalad could actually damage any pesky 3-threat enemies.
If direct damage from Argalad or Ranger Bows is not enough to finish off an enemy, there are options for using events to deal the remaining damage to kill an enemy. It has served me well in several of the Haradrim cycle quests where it is good to have extra ways to manage all the enemies in multiplayer.
