So I just whipped up this battlecry-based low-cost aggro shaman deck, and had alroght results so far, but I've mainly had trouble with the efficient removals of enemy rogues and the early game buffs of priests. Any idea how I can make this better? I'm trying to break Rank 15 at the the moment, and I have all wings of Naxx (including class challenges), and wings 1 and 2 of League of Explorers.
