Hearthpwn

This deck took me to legend pretty fast. It has a very hard time with Warlocks (need to go as aggressive as possible) because it can't out-value. Other than that, it can pretty easily handle all other classes that don't have the nuts from the word go.

It can struggle against Deck of Lunacy Mages, but against non-lunacy Mages you just out-value them while keeping you life total up until they run out of gas.

Against Warriors and Hunters, Hysteria is key. Focused Will is also really useful, not only to negate things like Paladin buffs, but also to create the right math for Hysteria. It's fun when your opponent takes the effort to play around Hysteria then you ruin than with Focused Will and erase their board.

What I like about the deck is that it makes for a different game, every game. It's less random than Deck of Lunacy, but you never know what you're gonna get so you have to craft a win condition that, more often than not, is doesn't look at all like your last game.

 Sometimes Kazakus will sit dead in your hand because Blademaster Samuro is still in your deck, but the value for each of them is too good not to occasionally have 1 dead card in your hand.
