Shadow and Flame Fellowship
The goal of these decks is for Deck 2 to use Song of Eärendil to (hopefully) keep Deck 1's threat at 0, so Durin's Bane is only attacking one player, instead of both. Deck 2 spams out as many allies as possible to deal with DB and enemies. Once Deck 1 is powered up with Dwarven Axe, Erebor Battle Master, Khazâd! Khazâd! and Heavy Stroke, it should be able to take out DB.
