Hearthpwn

This deck is all about building up a big mech to get an OTKO or to get a series of large attacks. 

By using mechs instead of single large minions you can build up your minion over a few turns and have it to ready to attack without needing Charge, since you will often start with something like an Unpowered Steambot or Unpowered Framebot as the base and then Magnetize on to it in later turns.

The Silences are in the deck to get rid of a pesky taunt if needed, allowing you to attack face.

Lady in White could be put in, but may come too late. The key to this deck is setting up for very fast OTKOs or 2TKOs using either Inner Fire or Topsy Turvy. Ideally you are hitting the face for 20+ damage by turn 4 or 5, before too many ways to stop you can come into play. 

You can generally hit for 20+ by turn 4 or 30+ by turn 5. Sometimes it's better to go for 2 or 3 smaller hits, but generally you want to be able to hit for at least 15 on a given attack to make it a 2TKO, that way if you're attacker gets destroyed (Polymorph, Hex, Assassinate, etc.) you only need 1 more hit to finish the game.

In worst case scenarios Wargear can be used to try and finish off an opponent more traditionally if needed.
