Hearthpwn

An interesting deck that's performed far better than I thought it would when theorycrafting it. 

Play-style is pretty straightforward: Mulligan for whatever gives you the best shot at making it to turn 6 (Generally Call to Arms and possibly Vicious Scalehide or Wild Pyromancer), then from turn 6 on play big taunt after big taunt after big taunt until your opponent either runs out of ways to remove them or you can set up an Uther of the Ebon Blade combo finish.

MVP's of the deck are Vicious Scalehide, Wyrmguard and Sound the Bells!.

Vicious Scalehide is a great card in the early game for countering aggression, but in a deck like this with buffs up the wazoo, you can make incredible one turn tempo/life swings that utterly decimate burn based decks. 

Wyrmguard is another highly powerful card in this deck for two reasons: it baits out silence type effects and has incredible synergy with Primordial Drake. Turn 7 is a make or break turn. Playing a big disruptive taunt minion on 7, especially having just played a Sunkeeper Tarim or Spikeridged Steed the turn prior, can save you from imminent death, and Wyrmguard is the definition of big and disruptive. It's  enormous health pool not only ensures that the opponent generally has to spend a lot of expensive / limited resources removing it, but also makes it liable to survive following it up with a Primordial Drake clear. 

Sound the Bells! is the real show stopper though. Generally you won't want to cast it until you're sure you can get 3 or more casts out of it, with the sole exception being whenever Wild Pyromancer is involved. This card combo's beautifully with Pyro in the early to mid game, serving as a somewhat impromptu consecrate that also has the benefit of making Pyro a 5/4 or more. It also combo's incredibly with Vicious Scalehide, letting you make upwards of 5 health swings off 10 mana, something that spits in the face of burn. But it's true calling is the Uther Horseman "soft combo", which will be explained later. Flexibility is this cards forte, so don't be afraid to think outside the box and get as much value as you can out of it.

The 4 Horseman Soft Combo

While you do end up making a lot of big minions, most of them aren't the greatest at damage dealing sans buffs. The REAL way you're probably going to win most dedicated control match-ups is through, believe it or not, Uther of the Ebon Blade and his literal game winning hero power.

Aside from actually drawing and playing Uther himself, the soft combo is a "2 turn" setup that always takes the following form :

Setup Turn 1: Play a Big Taunt Minion and Hero Power (1 Horseman). If either fails to survive to your next turn, repeat this process until both of them do, occasionally taking time to clear against your opponents board, then proceed. 

Setup Turn 2: Hero power, then play Sound the Bells! to buff the two horseman you have outside of the range of whatever possible board clears / target damage your opponent might have left. Off of 10 mana, you can make two 4/6 horseman, which is usually enough to survive every non-variable damage dealing clear.

Finisher: Hero Power, then play Blackwald Pixie to Hero Power once more for the auto kill. 

It's surprising how hard it is for other control decks to combat this, even the usual ones you'd think would have no problem like warlock and priest. It's very rare that an opponent will prioritize killing the first horseman, which is really the whole reason this approach works: if ever a single horse man survives to the next turn while you have Bells! and Pixie in hand, you're opponent will be in for a rude awakening.
