I can immediately see I need to ratchet back the land a bit. Not much, but one more playset of something should do nicely.

You don't need Nykthos, Shrine to Nyx in this deck. At most you're going to be adding 1-3 of each mana color at any given time from your devotion symbols and even then you have to spend two mana to do it. I'd take out both of them, take out one of each basic and put in 3-4 Mana Confluence .

Good point! Had Nykthos, Shrine to Nyx In there because the previous iteration of the deck was gruul ramp and I'm working on a budget from what I have on hand, but that's an excellent point. Playtesting has at best given me a yield of 2 mana from Nykthos, but color requirements are more likely a problem. Thanks!
