Hearthpwn

First off, I'm not going to straight up lie to you like most of these other guys on this site and tell you this deck is 90% win rate, because it's not. At earlier ranks, you might be able to do pretty well, but once you are playing against other 2-3 star master decks, you're going to be winning about 60-70% of the time. 

The good news is, games with this deck are fairly quick. You can pull off your winning turn usually by turn 8 or 9 at the latest. Also, this deck has 0 Epics and 0 Legendaries, meaning it's extremely easy to assemble the full deck list. I have a pretty complete collection, so it's not because I don't have epics and legendaries, it's because this deck is at its best as-is.

So, the win condition for this deck is fairly narrow and straightforward: Stall with your traps and removal until you get a specific combination of cards. Preferably (in order of importance): Buzzard, Dragonhawk, Timberwolf, and Unleash the Hounds. Yes, you absolutely need Unleash to pull off the attack, but it's not quite as important, because if you have the 1 cost dudes in hand with the buzzard, you can probably draw an unleash if you don't already have one.

Obviously, if you're not an idiot, you already realize that you almost never play any minions with this deck until the turn that you lay down this combo. The only exceptions being playing an Owl to silence a huge threat, or sometimes, playing a Boar to get 1 damage in to kill something. In these situations, having a Kill Command in your hand to do 5 more damage is also nice, since you will usually not be playing it on your winning turn.

I'm not going to sugarcoat it, this deck requires some luck. Sometimes, you have 3 cards in hand and you know you will lose next turn if you don't get a lucky draw. Fortunately, if those 3 cards are buzzard and 2 1 cost beasts, and they are sitting at less than 15 health, you actually have a pretty good shot at winning. Just keep in mind you don't always need to have the winning cards in hand to win with this deck. If you have 8+ mana crystals and buzzard with a couple of 1 cost beasts, you could easily draw into what you ned to finish the job. Tracking and Flare also help you get what you need.

Things to keep in mind: 

1. The most important card you can possibly have in your opening hand is Eaglehorn Bow. That thing is incredible. If they don't Ooze it, you could potentially have the bow the entire game and swing 6-7 times with it due the number of traps in this deck. 

2. Try to have an opening hand of mostly traps/removal with a bow. That's the ideal hand. Traps are more important than other removal because it fuels your bow, which is removal AND damage to their face. If you are going second, having 1 high priority combo card like Buzzard or Dragonhawk in your opening hand is fine.

3. Use the crap out of Steady Shot. I can't stress this enough. Even if you have another play, try to use Steady Shot at EVERY opportunity. You will Steady shot on turn 2 almost 95% of the time. The only time you wouldn't do it is if they have 2+ minions out and you have a Explosive Trap in hand. Thus, typically, you will not be playing traps until at LEAST turn 4, when you can trap AND steady shot. 

4. I usually save The Coin unless I'm absolutely forced to use it. Why? because The Coin can be really crucial to a successful OTK (One turn kill) 

5. Know what kind of threats the opposing class has available. For instance, you can freely toss your flares against Shamans and Warriors for the most part, but you might want to hold at least 1 back against a Mage or Hunter. (Especially hunter) I can't tell you how satisfying it is when a mage thinks he's won (spamming "I'm Sorry") because he's got ice block out when I'm laying down my OTK combo, and then I drop Flare. This has actually happened to me 3 or 4 times. Seriously, once this happens to you, you will know what I mean. Also, if you opponent has a lot of taunters, hold back your Owls, because you will probably need at least one to break through for your OTK.

6. Know when you need to try to win. The point of the deck is to stall until you can lay down the combo. The longer you wait, the better your chances are of getting the correct combination of cards to pull off the OTK, but you need to know when to go for it. If a Mage has you at 11 or 12 and it's turn 8 or later, you might want to just go for it, because next turn he might pyroblast you in the face. Be aware of how much damage they might be able to do to you next turn.

7. Don't be afraid to drop the combo even if it won't win the game that turn. Sometimes, your board position just sucks and you didn't get enough removal to secure a decent position. If you're going to lose next turn if you don't do anything, just drop all of it out there and try to kill off what he has. Don't just give up. Many times, a situation that looks unwinnable turns into a victory because of the cards that you end up drawing from Buzzard.

8. Be smart when you use tracking. The 2 cards you don't pick are going to be discarded. So if you see 2 Unleash the Hounds, you are going to HAVE to take one of them, no matter what, because if you don't, you're not going to have any left. If you have alot of of you OTK cards in your hand, then maybe you might want to get some traps or removal. If you have alot of traps and removal, you probably want to try to get one of the OTK cards. For the most part, you will want to try to get the high priority OTK cards, especially Buzzard, Dragonhawk and Timber Wolf.

9. You only really need 1 Buzzard, but sometimes, having 2 Buzzards can pay off. I wouldn't recommend playing 2 Buzzards unless you have 9 or 10 mana though.

Ok, so, that's pretty much it. I used this deck almost exclusively to get to 3 star master, so if you play it correctly, you should be able to do it as well. Don't just copy this deck list and comment that my deck sucks if you didn't play it like I told you to. If you think you can make my deck better, feel free to switch up a couple of cards, or comment and let me know what works for you. I might even change my list if I find that what you use works better. Good luck, and happy hunting!

P.S. I know for a fact that they are going to be nerfing unleash the hounds in the next balance patch, so don't go out of your way to craft cards and stuff to make this deck. Enjoy it while it lasts.
