Reno Mecha'thun Hunter

The deck's win condition is self explanatory. You wanna kill your opponent with Mecha'thun. How? By using Hunter's Mark and one Rapid Fire on him. For this combo to be pulled off, you need a cost reduction from Emperor Thaurissan for all of the combo pieces. If you draw Mecha'thun through Jepetto Joybuzz, you can ommit reducing the cost of your cards, potentially saving you mana to throw away some of the cards that clunk up your hand.

The difficulty of doing this in Hunter is surviving the early game and drawing enough cards to quickly pull off the combo. Luckily, there is quite a lot of card draw within Hunter and Neutral sets, with Subject 9 working wonders in that department. You can obviously pull off Secrets with other cards like Phase Stalker. In terms of survivability, the highlander package should be more than enough to sustain you, and it lets you play some more sustain cards. [Hearthstone Card (Zephrys) Not Found] is your trump card for every situation you need.
