Hearthpwn

This is a variant on the typical Malyrogue, running very few creatures, tons of spells, two Gadgetzans and a Sprint for good measure. The goal? Build some tempo with early value plays like SI:7, Tomb Pillager, Edwin, and Xaril, stall the midgame out, draw through your deck for Malygos, and go for the throat with a massive OTK. 

Why greedy? Because I'm running more burn than usual, no heals, and very few early-game creatures. The deck is extremely spell- and draw-heavy, aiming to sneak in a little damage early on, and then go for a fairly quick lethal with Malygos. Interestingly, though, you can get an absurd amount of damage from your spells even without him.

If anyone's interested, I can go more in-depth with matchups, mulligans (short version: mulligan hard for backstabs and SI:7s!), and more, but I have had quite a lot of success with this deck in casual play and some success on ladder (although my sample size there is still relatively low). 

Why no Bloodmage? Because I don't have him. Replace a shiv with him if you have it.
