The goal of the deck is to play a minimum of 5 lifedrinker and/or nightblade; reduce the cost of murmuring elemental with fire plume harbinger and, with ten mana, play murmuring elemental for one mana and shudderwock. The battlecry of shudderwock will deal six damage to the ennemy hero for each lifedrinker or nightblade you played in the game, because the battlecry trigger twice.
