My Plangeldrazi Deck

[Coolie2]

For a while I have been trying to improve my Green White Planeswalker-Angel-Eldrazi Deck. I have recently adjusted it to make it a 100 card singleton deck, and think I have finished adjusting it. The one thing I'm not sure about is it's mana ramping ability as it needs to be able to get a lot of mana quickly. Any suggestions on what to add or remove to get more mana quickly or suggestions on what to add or remove in general would be helpful.
