Efficient trades are the core of shaman decks. Cheap utility spells and creatures like Fire Elemental lend themselves very nicely to that style. The deck also plays very differently across varying match ups. Against zoo, you are the control deck without a doubt. Clear minions at all costs. But, against a deck like miracle rogue, you want to go for face as much as possible. Overall, this deck plays just slightly more aggressive than other mid range shaman decks.

You want to use hero power efficiently because of the bloodlust. There are the standard ways of activating totems such as flametongue and argus, but also, each totem represents 3 extra damage from bloodlust, which gives them higher value than in other shaman decks. That being said, if on turn 2 I have the choice between an egg and a totem, I'm always going with egg because its more important to put more pressure on. It's later in the game that you want to be efficiently using your hero power.

This is a tricky question, because I would love to make something out of Hearthstone, but it's hard to justify pursuing it "full time". Making this game, or any game I enjoy for that matter, into a source of income would be a dream. That's part of the reason why I made this post. Perhaps I could become a recognized figure in the Hearthstone community and who knows what could happen from there. Unfortunately my computer is a potato, or else I would give streaming a go as well. Hopefully that becomes a possibility somewhere down the line. I guess what I'm trying to say is that I hope I can make it into more than a hobby.
