Hearthpwn

Step #1 - Draw Galvanizer x2 and Bloodbloom x1

Step #2 - Draw Hemet, Jungle Hunter + Destroy Remaining 1-3 Cost Cards.

Step #3 - Draw Until Deck Is Empty

Step #4 - Play Mecha'thun (8) + Bloodbloom (2) + Cataclysm (4 Health + Discard Hand)

Special considerations:

1.  If Hemet is hiding in the back of the deck, you just have to play through.

2.  If Mecha'thun shows up early, you can play Galvanizer x2 as they show up.  Sometimes they show up close to each other, in which case you can usually afford to play them together for (3) instead of (4).

3.  Watch for Bloodreaver Gul'dan as your health is usually pretty low when he shows up and he gives you a push to get through the final turns.
