Hearthpwn

This deck is insane against every actual meta agressive deck while the combo is only here to beat greedy deck.

Unfortunately his worst match up is against every warlock who use Bloodreaver Gul'dan, because he will simply eat your Horseman, unless it is his last card your chance to win are pretty low.

Against agressive deck, mulligan for Righteous Protector,  Consecration,  , Knife Juggler,  Benevolent Djinn and taunt card, if you have the coin you may keep Call to Arms.

Against mid/control, mulligan for Call to Arms , Truesilver Champion.

How to play the deck :

We use Ancient Brewmaster and Gluttonous Ooze instead of their lower version because we don't want them on Call to Arms.

Against aggro, simply taunt, trade, clean the board with spell when necessary, also try to keep your  Benevolent Djinn alive. If you draw Blackwald Pixie simply drop it, the body is very good. If the game is still during for the late game (against aggro paladin) you can use Ancient Brewmaster on your Primordial Drake and laught at him.

Against mid/control, don't overextend unless you have the opportunity to win by being agressive, keep Ancient Brewmaster to use it on a Horseman. Keep also Blackwald Pixie for the otk combo.

So how to otk :

You will need a Horseman in your hand that you got from Ancient Brewmaster, you will also need one Horseman alive on your board which is hard but not impossible. It also need to not be the same Horseman that you have in hand. Now you can simply drop your Horseman from your hand, hero power, Blackwald Pixie , hero power and you win. It is very tricky but very possible because of the multiple taunt of our deck. 

You can see here the synergy with the taunt being able to destroy aggressive deck and also makes the combo possible to beat control deck.

Have fun.
