Hearthpwn

Intro

Control the board, gather pieces, pwn your enemies!

Gameplan

There are 2 options:

1) Play as secret/spell hunter if you happen to mulligan Lesser Emerald Spellstone + secrets. Try to end the game asap if you get direct damage cards like Candleshot, Eaglehorn Bow and (copy of) Clockwork Automaton.

2) Alternatively, against control, you can mulligan for/keep draw cards and focus on getting the combo asap. Best is to spend your draw first then use Stitched Tracker/Master's Call to grab the remaining pieces. Stitched Tracker can also be used to get an early Emperor Thaurissan discount on cards already in your hand. As an extra copy, it's just an added bonus on curve sometimes.

The follow-up also consists of two substeps:

(i) Play Fencing Coach on a turn before you play your OTK. It's possible to play him on the same turn as Emperor Thaurissan, but remember not to use your hero power (HP) if you play him long before your OTK turn. Followed by

(ii) the combo itself is: Clockwork Automaton -> Carnivorous Cube -> 2x Play Dead -> 1 x Feign Death -> HP. This gives you 6 clockworks and a 2^7 (128) dmg hero power. Even with 2 activators it usually works.

Substitutes

1 x Feign Death can be replaced by 1 x Terrorscale Stalker. Since you can only play 1 Terrorscale Stalker with a Emperor Thaurissan discount I put only 1. The advantage is that you can pull him via Stitched Tracker, downside is that he prevents pulling other minions via Tracker.

Using Terrorscale Stalker gives you space for one less Clockwork Automaton and *only* 64 HP dmg potential, but it means you do not have to craft the more expensive Feign Death. In most cases double Play Dead, or 4 Clockwork Automatons is sufficient (32 HP dmg).

You can exchange 2 x Master's Call for 2 x Doomsayer. Sacrificing 'discover-draw' for board control. Budget option is 2 x Tracking, which is then only there for digging for your final combo piece because of discard, so do not use it beforehand -- or at least do so at your own risk or if the game is otherwise lost.

Zul'jin is not necessary, but his hero power also works with this build. You can also play (a discover copy of) the Clockwork Automaton to snipe minions with your hero power in case of emergency. He can be replaced by another Hunter's Mark or Deadly Shot, which might give some more clearing power.

Secrets can be interchanged based on what you have, Freezing Trap or Bear Trap are nice alternatives for giants or agro, respectively. They are mostly there so that Subject 9 can thin your deck faster.

If you are seeing only control (sure..) then Deathstalker Rexxar could be added to the pool as a backup for late game. He makes the deck pointless due to his hero power, but also shifts the game plan entirely. Of course, he could be played before Zul'Jin, so you can still do the combo. Not a bad addition in exchange for Unleash the Hounds or Explosive Trap.
