Hearthpwn

 Have you ever wanted to slowly drain the moral of your opponent and eventually let them die alone in fatigue? If you said yes (which why the hell would you not want to do that, unless time reasons), then this deck is for you.

With the addition of Forest Guide and Ferocious Howl and the help of some wild symmetrical card draw such as Coldlight Oracle and Grove Tender, mill druid is now able to slowly draw your opponents deck until they die a slow and painful deck in fatigue while you stay safe with the help of everybody's favorite Jade card, Jade Idol.

With the advent of Mecha'thun I thought it would be fun to try and get a more reliable win condition. Now instead of one the Jade Idol and one Wrath, we have a Mecha'thun. The deck works the same way but instead of having to rely on Jade Idols to finish people off, now just play Mecha'thun then Innervate and Naturalize after you've drawn everything and emptied your hand. Not sure if anything else really needs to be changed, but I'll update the list once I find out. Edit: On this plan I took out Ultimate Infestation for a Biology Project because it gets stuck too much in hand.

Forest Guide is without a doubt my favorite card in the expansion so far. Not only does it look defenseless, being a 1/6, but it's also a huge powerhouse in terms of mill. Sure it lets your opponents play their card first, but it doesn't matter as long as his hand is flooded to oblivion. If your opponent kills Forest Guide the turn it is played (which is often not the case for the first one played), you are still able to force your opponent to draw 12 cards, giving you plenty of burst to annihilate your foe in fatigue.

Another important card in the deck is Ferocious Howl. In this deck, this card is able to consistently get 7-8 armor. This lets you stabilize/be more aggressive with your hero, while also cycling cards to get to your draw.

With the current list, you can either go the Jade route of just creating a lot of Jade Golems or you can go the Mecha'thun deck and otk your opponent. The deck probably would do better but it plays around Demonic project and other combo disruption.

Substitutes

If you want to replace Mecha'thun, you can go back to the previous version of this deck by cutting Innervate and put in 1 Jade Idol and one Wrath in it's place. Also take out Biology Project and replace it with Ultimate Infestation if possible.

If you want to replace Malfurion the Pestilent, another Acidic Swamp Ooze. Sadly there is no great cut for this card simply because it does so much.

Final Verdict

I'm not a great player, especially in wild. As such, I'm not the highest rank (mainly because I don't play it, but nevertheless) and so you might have the deck not work at all in higher ranks. However, the deck should still be able to demoralize most forms of warlock. A true mill player doesn't play to win, they play to make the opponent feel worse then them.
