Hand of Gul'dan Zoolock

Relies on the combo of [card_link name="Expired Merchant"] / [card_link name="Nightshade Matron"] and Hand of Gul'dan, as well as [card_link name="Imprisoned Scrap Imp"] to have the powerful tempo and board flood you love from Zoo warlock while keeping your hand nice and full.

It is pretty aggressive and your main way of getting back on the board are cards like Matron [card_link name="Frozen Shadowweaver"] and [card_link name="Maiev Shadowsong"], but can have trouble if you get behind and manage to miss your card draw.

[card_link name="Darkglare"] is also an impressive card for big tempo turns and can help you dig a little quicker for your broken stuff.

I'm sure there's some tweaking that can be done, but I managed to hit Diamond so far primarily using this deck and hope to climb higher.
