As a side note, the Furyborn Hellkite is Galbatorix. Lightning bolts come from his spear; and the spear is the salt slayer.
In terms of deck construction, I'm at the point where I'm thinking of more things to add before I start trimming the fat.
Looks like it might need more early game red and/or late game white. Not sure where I want to split on the red to white ratio.
I think it might need more creatures to shtick on the battlefield for mid-game defending and attacking.
With yours, the Angel of Glory's Rise could be maybe board. Here is the protoype i built for John, http://tappedout.net/mtg-decks/dellingr/. I like the Disenchant and Swords to Plowshares, but the Furyborn Hellkite might be too much (strike that it is). Battle Hymn works better than Geosurge in this case because with all the small costing humans you'll get more red mana out of it. Plus since you're running 2 colors, geosurge would probably not see as much action. Soul's Fire with Malignus is very potent as well.
