I’ve always been a fan of the Hunter class – SMOrcing, playing midrange decks, or just messing around. Although Hunter’s been in a bad spot for the past few expansions, I’ve still managed to come up with some crazy deck lists, so here’s one of them. I designed the deck specifically to focus on the midrange style. Even though it doesn’t really look like one on paper, it’s a whole different story in the game. Each mana slot has around 2-7 cards, therefore your chances of drawing a card from one slot is pretty high. This helps you build your early-mid game curve: 2 drop into 3 drop into 4 drop, etc. Plus, most of these cards are all midrange cards – they help you take and maintain control of the board, while occasionally playing some value cards like Arfus or Corpse Raiser. If you eventually lose control of the board, you have your trap card: N'Zoth, The Corruptor.
Edit: -1 Corpse Raiser +1 Elise the Trailblazer. Both cards have the same purpose in the deck, but Elise does a better job of sustaining in the late game, is more consistent, and provides more value than Corpse Raiser.
Against heavy control decks like Reno Warlock or Control Warrior, you generally want to go with your curve as much as you can. In the mid-late game, when you get Deathstalker Rexxar, play it as soon as you can. The Hunter DK hero power just generates so much value over time while consistently pressuring your opponent; all that matters in the late-late game when you’ve played pretty much your entire deck is your hero power.
Against aggressive decks, cards such as Jeweled Macaw, Mad Scientist, Eaglehorn Bow, Deathlord, and Rat Pack (your general mulligans) can absolutely stop them in their tracks. Plus, if everything else fails, you’ve got Reno Jackson and Antique Healbot for backup. You have so many anti-aggro cards that aggressive decks that assuming you get decent mulligans, you can destroy aggressive decks.
Honestly, the only bad match-up I can think of is against Priest. Dragon Priest can manage to out-tempo you if you get bad draws, and the super-greedy Reno DK Quest Priest will eventually beat you only because the Priest DK’s hero power does way too much damage; it’s like Hunter’s hero power on steroids.
You can pretty much beat everything else though. Against Freeze Mage, you have Antique Healbot and Reno Jackson. Against Druid, you just play along your curve and out-tempo them. Against Warlock, you go along with your curve and play Deathstalker Rexxar as soon as you can so that you can start spamming high-value minions, although you’ll lose to Warlock if you have a weak board. You guys get the point: the deck is just crazy. I’m not 100% sure whether it’s good or not, but it’s definitely really, really fun.
