Three-Headed Burst!

this fellowship is untested. Also, consider straight-swapping Mirlonde for Haldir, this gives each of the respective decks a slightly different dynamic as the Elven Trio deck loses a "ranged" hero and takes some of the versatility away from "Hands Upon the Bow". However, the Ranger deck then gains a stronger hero, additional ranger and ability to attack the staging area (where hopefully several trapped enemies will be). This at the cost of 4 threat overall. Try both ways, see what you like.
