Also, don't feel like the two Pyroblasts are a requirement. I only had one so I put a Blizzard in. Just pick high damaging or AOE spells for when the adds get overwhelming.

This indeed isn't a very good deck. I made some modifications I think helped.

I ripped out the Mana Wyrms and put in Sorcerer's Apprentices. Reducing the cost of spells is a huge plus in this fight and I found the Mana Wyrms didn't live long enough to do anything useful, or the taunts prevented them from doing anything meaningful.

I also took out the Earthern Ring Farseers and put in Dalaran Mages. The heal just never really seemed to help. If I was at the point I needed to heal, I was dead anyway. The mages give you a +1 Spell Power and since they have 4 Health they are quite durable.
