Source: Hearthstone Top Decks Article
Nice roundup that covers everything we've seen from tournaments so far. It had quite a lot of decks I posted but I did not find a notable Hunter deck and this article listed one that I think looks quite good; Jab's GvG Midrange Hunter. No Gah'zilla used but has Dr. Boom which is showing up in a lot of decks. The other minion that I think had improved quite a number of decks is the Antique Healbot which did not get a mention.
