For added deviancy you could include Niv-Mizzet, Dracogenius . For extra mana fixing I'd recommend including Sulfur Falls as that will help you cast your spells more often. I'm not too sure whether this deck works or not but worst case scenario might be that you can't land the last few points of damage. Maybe an Elixir of Immortality or two to at least guarantee some recycling in your graveyard?

Also, going to chime in with some other suggestions, just because I thought of them:

Pyroclasm , Volcanic Fallout , Slagstorm , Inferno , Earthquake , and Comet Storm , are some good cards to consider. Also, Seismic Assault can be good too. If I have more sugestions, I'll post again soon!

Thanks for the comments folks, especially that Breath of Malfegor . The others aren't quite as good because I don't want to be hitting myself with my own spells since the deck isn't well defended against creatures. Elixir of Immortality is a good idea as well, but perhaps putting in one of the Eldrazi titans would work better since I don't have to use mana to return my GY to my deck.
