Its a pretty fat deck, and the draw power is pretty weak.
If you want to keep a similar form I would say get rid of your Eternity and Devonian and add another hourglass or two Right off the bat.
I would suggest slimming it down a bit more by taking out cards that are only there as counters (Purify and Jade) and also your azure (focus on the blitz). Chimera is actually a really strong card here, so I would suggest -colossal +chimera.
Your fire shield/SoG defence seems like it would do ok, but I've never played it so I'm not sure.
Personally, I prefer sundials and dims. Sundials help speed up the deck and dims make better use of
than phase dragon IMO. You could also probably afford to take out some SoGs then to help slim it some more.
