Maybe Try Building Up From This Point B-W...
Ok, I'm not really sure the proteus belching method is neccassary. Just as good old fashioned solid constructive criticism, I think you should try building your deck based arround the above posted idea. Oviousely I'd love to see it look much better and much more unique than this one, but I've tested the two decks and this one is just smoother. creature threats are your biggest issue here. this base model I've designed for you includes the following...
1)Mana Excelaration
2)Spell Coppying (useful and nasty spells at that)
3)Searching for the gates and idols and sceptors
4)A way to clear the board and keep your threats
5)A way to counter an 11/11
6)A way to generate creatures in a pinch
