It's a good ideea to start with Lesser Jasper Spellstone, because you can easily upgrade it with Ferocious Howl, or Malfurion The Pestilent's Battlecry / Hero Power.
Doomsayer it's good against early aggro.
Also, if you manage to get both Witchwood Apple and Mountain Giant, by turn 3 or 4 you could play an 8/8.
This is the deck that I’m currently using. If you don’t like using 2 Naturalize‘s, you can either use a silence minion, like Spellbreaker or Branching Paths.
