This is a multiplayer deck. It can defend and attack pretty well right from the beginning.
Beregond is meant to get a Gondorian Shield, Armored Destrier and The Day's Rising.
Legolas should get the first Rivendell Blade or Bow of the Galadhrim (if no Blade is in sight) as well as a Rivendell Bow and Rohan Warhorse (don't give him two restricted weapons!). Support of the Eagles works best on him also. Be sure to keep a Vassal of the Windlord around in the early stages, so Support of the Eagles can be used to boost his attack. Any excess weapons can go to the Galadhon Archers (or suitable heroes of other players, of course), who can become quite formidable assists that way.
Háma is mostly there to recycle Foe-hammer (and maybe Hands Upon the Bow or Behind Strong Walls, if needed). He will get a Rohan Warhorse as well (so he can keep up with the other two on their mounts).
Song of Kings is in there mostly to have something decent to reduce Threat (namely Sneak Attack with Gandalf), and because Armored Destrier is so awesome. The Song of Kings goes to one hero (usually Beregond) whose resources are always spent last. Steward of Gondor will go on the same hero.
