A standard Discard Warlock list except I am of the strong opinion that Expired Merchantt is a bad card to include in this deck. It's best hit before was Fist of Jaraxxus to do multiple instances of high damage. With the removal of the card to make room for Wicked Whispers, the best hit is now Hand of Gul'dan, which is arguably TOO much draw and unnecessary. And having multiple Doomguard's is just redundant since you'll very likely discard one with the other. That leaves just Nightshade Matron, which isn't that good if you don't have a Hand of Gul'dan to discard.

With Wicked Whispers and Boneweb Egg's innate synergy that helps you go wide or even have protection against AOE, I think this is the better version by quite a large margin.
