I tried to plays lots of different shaman decks, using the beginner cards(lvl 10), but it was hard to make a good one.
I've played lots of games where I ended up with 25-30, and the enemy with 5-15, but after that I realized that I could do nothing else.
After I made this deck, this scenario changed.... a lot
In order for this deck to work you must focus in 3 things:
1.control the board early game, it shouldn't be hard with cards like feral spirit, flame tongue and forked lightning and totemic might.
tip1: if you flametongue and totemic might, if you get the coin, use a the hero skill to summon a totem, on the second turn use the flametongue, and attack with the totem you summoned before and if you have totemic might, USE IT. Take care of flametongue, with it in game you can just play using the totems, this way you keep the card advantage.
tip2: Becareful when using the Feral Spirit, it can make your next turn useless, try to use it on turn 3, this way next turn you can summon a totem.
ps: the objective of these cards is to have at least 3 cards in game in order to use the bloodlust.
2.save the rockbiter weapon, windfury and reckless rocketeer. They are your finishing combo. You can do even better if you have fire elemental or stormwind champion already in game.
ps: if you get 1 extra card of the combo, use it to kill the taunt or to lower the enemy hp if it's not low enough.
3. Know how to place your minions/totems on the board.
Good Luck =P
