Hearthpwn

This isn't a free to play deck, but it requires a lot less dust than most of them.

If you're climbing the ladder and facing a number of warriors and control decks, then this is a great little hunter deck.  Maybe some of the other midrange decks are better at higher ranks, but those acidic oozes are extremely helpful.  Cookies and creme kudos to Trump.
