Warlock
This is a Year of the Raven Standard Handlock. The idea is that Genn Greymane‘s discounted hero power will let you draw into your answers and have a better mid game more consistently then a 2 mana hero power. However, with N'Zoth, The Corruptor rotating out and many of the more powerful demons having odd numbered mana cost, it will be harder to win a drawn out value game. Also a reminder that there is still a full expansion of cards to see and that there may be better options in the days to come!
