Hearthpwn

Deck i used to push Diamond 5 - Legend.

PRO:  

-Can outvalue most other decks.

-Hard to kill once you get the sunken sabers rolling.

-Hard to counter.

CONS:

-Can be weak against non board based decks.

-Must change playstyle depending on what you are facing.

-Weak to silence, really countered by priest.

PLAYSTYLE:

Against aggro / board based:

You try to use the weapon dredge on a sunken saber or colossal from Faelin. If you don't have a 4 mana beast in hand on turn 2 - 3, play a selective breeder and get one, otherwise keep him for sunken sabers or colossals. 

You mainly play around Mountain Bears. Focus on getting dire frenzy on a sunken saber for more board control, or on a Mountain Bear for extra defense options. Ideally, you get one on a sunken saber and one on a bear. 

You can revive pet + dire frenzy for a solid 7 mana combo.

On short, you take the board and overwhelm them with taunts.

Against slow combo decks / quests priests / control:

Priest is this deck's weak spot, the 8 mana Whirpool will remove all dire frenzy copies we have in the deck, silence will counter our sunken sabers unless we can kill them the turn they are played, drown will remove our king krush from the ress pool. 

To win here, you must get a good tavish improved emergency maneuvers on king krush. The combo could be stormpike ram on turn 4, tavish with an empty board on our side on turn 6 and krush on 7 ( reduced by 2 from the ram). Trade krush into a minion to make it easy for the priest to kill it ( so he won't drown it).

On short, you need king krush to kill priests, against control warrior you can play the normal route, as you would against aggro, as they will run out of control before we run out of value. 

In general: 

Use devouring swarm on selective breeder and sunken saber, both at the same time, should not be too hard.

The stormpike ram is there against slow decks to play king krush early if you draw him.

Only play emergency maneuvers when you have good value minions on board, or you plan to play one next turn. 

MULLIGAN:

Selective Breeder for guaranteed turn 4 saber.

Azsharan saber.

Weapon is a keep, always.

Faelin is fine.

Dont keep any secrets, look for bunker.

EXTRA:

Marked shot is for gigafin, also might get you a good discovered spell.

We cannot use viper, it is a beast and will get pulled by sunken or pet collector, so we use ooze instead for weapon removal against paladins.

 You could add Hydralodon in, but he fills your ress pool with shit 3/1 minions. Also he is a bad pull from sunken when you need a quick answer, as the heads don't have rush.
