Normally I agree with SoulSaver. If you're making a deck for T1-MP then his advice is sound. But if you want this deck for T1-2P then I think he's steering you wrong. The decklist he gave you is great for his style of play but not for most people.
A deck with a powerful offense and defense will probably perform better in T1-MP. I point you to the top three decks from Nationals 2008 T1-2P as proof. All had a close to the same amount of offense and defense.
