Yeah, you're going to need a deck kinda revolved around him, which is why I think he's so balanced, but still good. Best case scenario, you get a 7/7 and three good minions instantly played. Worst case scenario, you get a 7/7 and get three weapons or something.
Personally I haven't put any money into HS yet but since I've gotten better as a player at it, recently in particular, I'm going to buy Naxxramas soon, namely for those cards like Spectral Spider, Nerubian Egg, Shade of Naxxramas, Kel'Thuzad, Sludge Belcher, etc. Basically the cards that make me think HS is pay to win (because on the ranked ladder I do well until I get put against Naxx/BRM cards). I really want some of the Blackrock cards, too, but namely just Thaurissan for the combos so I might just pay an extra two dollars more than what it would be worth in the full adventure for just the first wing. Not totally decided on that yet.
What's your Battle.net, Coco?
