Your deck has a set of particularly powerful spells, but running 134 cards slims your chances of drawing those spells. Why don't you consider building with the better cards out of your deck and dropping the more useless ones?
In tournament play, getting a threat on turn six is slow, not fast. Most decks can dispatch it with removal by that turn. I would cut it to 60 cards, to begin with.
A good hand for you plays Progenitus on turn six. A good hand for a more focused deck can easily win before that happens.

A very impressive and straightforward build. How does the single copy of Elspeth work for you?

Thanks for your comment! I did consider Hellspark Elemental when I was constructing Naya Aggro. And I look forward to seeing Lightning Bolt printed in M10. :D

I'll take a look at "Nexus Cascading." Thanks again.
