I am Pretty sure you can make this deck even better i am just giving an idea.
Before that you should need to low your opponent life to 20 health by the little minions you have.
Then the purpose is to have to have those cards in your hand:
then you put Hemet, Jungle Hunter and wait for cards, if you got
Holy Wrath and managed to get with it the Molten Giant so gr8. But, if not, so wait till you life will drain a little then put the other Molten Giant that will be out in a turn or two, then shuffle it in to your deck with Baleful Banker and use the second Holy Wrath.
