C’Thun Corrupt Priest [Forged in the Barrens]

This is a deck utilizing the Corrupt mechanic from Forged in the Barrens, as well as cards from the brand new Core Set such as Bloodmage Thalnos and Thrive in the Shadows for card draw. The pieces of C'thun, the Shattered are useful in this deck, as they can corrupt a large majority of the cards in the deck. Working with that, you can use Malygos the Spellweaver to draw into those C’thun pieces, as well as other Corrupt spells like Insight and Auspicious Spirits. Then, when you’re running low on value, you can secure the win by refilling your hand with 0-cost Corrupt cards via Y'Shaarj, The Defiler. You can also use Ysera the Dreamer to generate more value and possibly corrupt your higher-cost cards like Strongman. Finally, you can use Taelan Fordring to draw any of your Old Gods.

(And, if you’re looking to screw around, Yogg-Saron, Master of Fate is always a fun option)
