+Seer's Sundial
-Lifegift
Lifetotal is rarely a concern for me. Any way to draw more cards, however...

01/21/14
+Regal Force
-Seer's Sundial
While I didn't really get to test Sundial, I feel like Regal Force is going to draw more cards for less mana in the long run.

1/31/14
+Chord of Calling
+Tooth and Nail
+Craterhoof Behemoth
-Garruk Wildspeaker
-Words of Wilding
-Heartbeat of Spring

After adding Regal Force, I realized that my deck is starting to head in a certain direction, so I figured I'd give it what it wants. As far as my cuts, I don't actually own a Heartbeat (I'd been proxying it this entire time), Garruk is only really there for the +1 effect, which my creatures can do better thanks to synergy, and Words is really a placeholder for Abundance, and since I have yet to get a hold of one of those I just went ahead and cut it.

2/3/14
-Sylvan Primordial
-Tangleroot
+Courser of Kruphix
+Woodfall Primus

Considering the fact that SyPri got banned, he needed a replacement, and Woodfall Primus is the nearest thing to it. Courser was kind of a shoe-in and Tangleroot was the weakest link.

4/23/14
-Forest
+Mosswort Bridge

I got another one, so... Why not?

4/9/15
-New Frontiers
-Nature's Will
-Asceticism
-Forest
+Myriad Landscape
+Lifeblood Hydra
+Song of the Dryads
+Frontier Siege
Trying out new things. New Frontiers was a little too "group hug". The Hydra provides another source of card draw and another X spell. Song is excellent removal.

12/5/15
-rontier siege
+nimist's wening
