The Victory of the Dunedain

The Spirit/Lore deck, believe it or not, is for support. Glorfindel and Asfaloth provide some location control, along with Leave No Trace. Primarily you want the Victory Display to revolve around Keen as Lances, since Rossiel will probably do little to no defending, and willpower is usually pretty well covered.

Leave an enemy or two engaged with the Dunedain. You'll want it to trigger the effects, and then use Descendants of Kings to ready everyone and wipe the board. Fornost Bowman is great for this, as is Boomed and Trumpeted, which plays super well with Derndingle Warrior - deal himself 1 damage to get 4 attack, 5 defense, and action advantage to use both. I prefer to use the Ranger of Cardolan with Heir of Valandil instead of using his game text. I haven't found much need for an emergency defense, except in cases with the shadow effects of an additional attack. I'd rather pay 0 resources to get another body on the table.
