The spirit of Beregond

Try to get two enemies engaged with Amarthiúls deck as soon as possible (i.e. when Beregond has some readying) so he gets a Tactics icon and a bonus resource. Trap the two enemies with Forest snares. But remember that you can't use Dúnedain Hunter to engage enemies until Amarthiúl has the Tactics icon (already being engaged with one enemy).

Amarthiúls deck engage all enemies and Beregonds response helps the Rangers deck from raising the threat too much. Galadhrims Greeting is usually for Beregonds deck.

When Northen Trackers/Rhovanion Outriders are not needed to clear out locations in the Staging Area they each have a respectful 2 if an enemy end up engaged with Beregonds deck.

Beregond: Armored Destrier x2 Unexpected Courage x3 Miruvor x3 Dúnedain Warning x3 Song of Wisdom A Burning Brand

Amarthiúl: Steward of Gondor Song of Wisdom Sword of Númenor x2

Silver Harp is only there for those games that you don't see Elven Light early on, to make sure that you can still use Arwens action without having to discard cards you would like to keep in your hand.

At late game, when you start end up with dead cards in your hand, the two Protector of Lórien goes on Damrod and Arwen so they can use the dead cards to boost their questing.

Beravor will usually quest for the first round or two, and after that she can help both decks with card draw. Damrods traps will draw a lot of cards for that deck so I usually use Beravors action to help Beregonds deck.

The Rangers deck have 53 cards but with the amount of card draw you got that is no problem.
