This battle was 100% won because of my two zero mana cards (that I lovingly refer to as meat shields) that I put out front.
They were the only reason I was able to attack my opponents tank. The void ability that the opponents tank had meant that my 1 magic attack just bounced right off.
And I'm so glad I threw Spirit Shaman in here too with stun.
Because of stun the tank got off very few attacks.
Yay for meat shields!!
