-Chord of Calling
+Thousand-Year Elixir

Chord is good, to be sure, but it's going to find another home. Mayael, however, is slowly being tuned to make better use of it's general, and she would love to start plopping in fatties ASAP! Plus, it works great with Elvish Piper, Capt Sisay, and Godsire.

-Fierce Empath
-Tooth and Nail
+Garruk Wildspeaker
+Illusionist's Bracers

I'm taking the deck in a more general-focused direction, and Empath runs counter to that idea, while Bracers plays quite nicely with it. I'm sad to see Tooth and Nail go, but hopefully Omnath will be able to make even better use of it.

+Karametra, God of Harvests
+Archetype of Endurance
+Bloomtender
+Forest
+Forest
-Zhur-Taa Ancient
-Eladmri's Call
-Madblind Mountain
-Grove of the Guardian
-??? not sure what else got cut...

Eladmri's Call was wanted elsewhere. I don't like how much Zhur-Taa helps my opponents. I needed more green sources, and I was pretty unhappy with those lands. Wanted to keep my ramp going strong, so Karametra and Bloom Tender made it in.

-Gyre Sage
-Captain Sisay
-Karametra, God of Harvests
-Hellkite Charger
-Darksteel Ingot
-Garruk Wildspeaker
-Naya Panorama
-Windbrisk Heights
+Sakura-Tribe Elder
+Knotvine Mystic
+Siege Behemoth
+Thunderfoot Baloth
+See the Unwritten
+Rampant Growth
+Plains
+Wooded Foothills
These changes are largely a result of lowering my mana curve, adding more ramp, and improving my mana base. The creature swaps were to improve the power of my army overall.
