Season 2: Rise of the Miracle Rogue
Just trying to do my daily, I ran into 4 of them today. I don't mind Miracle Rogue as much as Huntard decks because Miracle Rogues have some pretty defined counters. And even though their deck is built on cycling cards really fast, they can get hit by bad RNG which sticks their Leeroy, Shadowstep and/or Gadgetzan's at the bottom of their deck. Finally, Miracle Rogue is one of the hardest decks to play well.
As for gold, I'm sitting at 2,700 right now. In the last month I've only spent 200 gold to get enough dust to craft an epic I needed for a deck I wanted to play around with. I really wish they would release gold prices for Naxx though so I know how much I need to sit on. I'm guessing 500 per wing at the low end (and that seems really low to me) and 1,000 at the high end.
