The Battle of Carn-Dûm - V3
Basic strategy is same as Seastan's as described:
The key is to build AN ARMY OF SUPER DEFENDERS as below to survive the battlefiled, then counter attack hardly:
One Silver Lamp for Glorfindel with Light of Valinor. If you can bring up another one to the dunedain deck with Song of Travel, that's so perfect for your defending decision, like you can use Armored Destrier to discard the exactly deadly shadow cards!
