Hearthstone: Curse of Naxxramas - Noth the Plaguebringer (Heroic)

Noth's the first boss of the Plague Quarter, and he proves to be somewhat of a worthy opponent thanks to his ability allowing him so summon a 5/5 minions instantly whener one of yours is felled. Needless to say, minion heavy decks should not be played here, and you should instead you minion-light control decks to minimize the effectiveness of his ability. Freeze Mage would probably be ideal, but Ramp Druid, Handlock and the like also work pretty well. Just be aware that Noth has an exceedingly annoying AoE come turn 6 which will kill all minions on your board, so either be sure you don't have anything to offer by then, or stun him with a timely use of cards like Loatheb. For a F2P option, an Inner Fire Priest deck is always a great option, as Noth lacks hard removal for big minions, and you get access to both Death and Pain to deal with his.
