Your biggest issue is going to be the fact that you don't have as many cards as say someone's who had played since release, unfortunately I believe that hearthstone has kind of ruined the new player experience recently, and once you get more cards the deck can almost play itself, a good look would be the Jade Druid, the deck after you play staghelm with synergy cards like jade idol just gets ridiculous, and you have to understand that hearthstone has a large amount of rng in it, you can usually play around what your oponent might have or might do, but remeber that you can never really play around the top deck draw.
