Hearthpwn

With this deck I was able to get to the 5th Rank this season.

The main advantages are - its pretty fast (you can rank up quickly), you have a lot of options how to resolve the situation and its incredibly cheap.

The main focus of this deck is on "tokens" and is based on old Reynard's deck. The "tokens" are 1/1 minions that you really dont care much about. There are several spells and minions that benefits from either number of minons or ability to sacrify few minions.

You should keep the pressure and always clear the board and slowly putting health down whenever possible.

Few cards that I can say more:

Loatheb
This is best card for "finishing him". Lets say you are keep clearing his board effectively and you have board big enough (+ some spells) to kill opponent in 2 rounds. Then there is the best time for loatheb. Bring him to the board, at this time you dont have to clear all the board as enemy is very limited in using any supportive spells or clearing board spells and focus on face. Next round - finish him.

Dark Peddler
If not necessary/there is another card to play - do not rush him out. The discover card is actually great used at the moment you need it - based later on situation, sometimes you are missing i.e. 2-4 damage to finish off the opponent - he can provide it to you. Or of course, if you are missing 3-drop on 3rd round, dark peddler can basically do it with 1 drop minion.

Echoing Ooze
Maybe you are asking why the card is here or how to use it - its actually pretty good 2 drop on 2nd round. It creates you the bodies with 2/4 in total, there are two minions so it goes well early in game to keeping the controller (especially against some murlocs/silver hands) early on.

Nerubian Egg
Amazing card - for just 2 mana you get (eventually) 4/4, you can use it well with Power Overwhelming or EVIL genius. Also its good to put it on board if there is high chance that your opponent has some board removal spells that kills everything. This helps you keep the value even after these spells.

Gormok the Impaler
This is only legendary in this deck and when it comes in right time its very handy - keeping to clear board easily (even big bodies with 4 damage) and also providing 4/4 on board for next turn. You can however live without it (a lot of matches you win before 10th round) so you often dont see him in your games anyway.

Sea Giant
Probably the only card that is "must have" in this deck. Sea giants are often the one to win you the game. Often for just 0-3 mana you get 8/8 body which is so much value very easily obtained. You will also know how much the Sea Giant will cost after you summon some minions, so you can often play i.e. few lowcost minions before playing Sea Giant maximazing the value.
