I really like what I'm seeing here. I think there are a few things you could do to show up some of the awkward points of the deck.

Possibly the biggest issue I see is your mana base. Was this supposed to be budget? Definitely need Wooded Foothills. I think Embodiment of Spring is awesome, but it's a blue 1 drop 0/3 that this deck will essentially never be able to play on turn 1. How about Flooded Strand? Remember, the new duals lands have basic land types. That means you can use Flooded Strand to either fetch your basic Island for a turn 1 Embodiment of Spring, or you can fetch a 1-or-2-of Canopy Vista for a green source.

In reality, you should probably either add more blue to the deck or cut it altogether. I suggest trying more. How about Clash of Wills?

I also like the explosive potential of See the Unwritten. How about a couple Greenwarden of Murasa to return the See the Unwritten to your hand, for pure value? You could even return fetch lands to your hand with him. Pretty crazy potential, and very flexible. A few awkward point about See the Unwritten are: 1) You will have a hard time triggering ferocious (adding more Retreat to Kazandu may help with this); 2) There are only 2 Omnaths and 2 Whisperwood Elementals in the deck, so you don't actually have many good creatures to hit. Hitting Woodland Wanderer is awful because he doesn't get ANY counters. Your other creatures are low-impact for a 6-cost spell. (Adding another Omnath, Locus of Rage, a couple Greenwarden of Murasa, and possibly one or two more big creatures like Dragonlord Atarka will help you here).3) Beastcaller Savant doesn't help you cast it. This is also a pretty significant problem with Explosive Vegetation, which you would like to be able to cast on turn 3.

Finally, Evolutionary Leap will be greatly improved by adding more big creatures, as discussed above.

Good luck, I hope some of this helps!

torimino, I really do appreciate the suggestions, and you have made a couple flaws very clear to me.

One of the biggest concerns you've addressed was the Ferocious trigger of See the Unwritten. Funny thing about this card is that when initially creating this deckllist, I had two spots open that needed to be filled. Greenwarden of Murasa was actually the first to come to mind considering that I was looking through BFZ exclusive spoilers. I threw him in but realized that maybe the deck could benefit more from See the Unwritten rather than Greenwarden. I may be wrong, but the only testing I've done has been through Tapped Out's "Playtest". Now I do have my eyes on Greenwarden, and I'm very glad you suggested him because adjustments do need to be made for a powerful utility card such as Greenwarden of Murasa.

Back to my point about Ferocious, I did look over my decklist and did notice only 7/20 creatures being creatures that start out with a power of 4 or greater (not including Undergrowth Champion). It does seem like a bit off balanced if I was hoping to trigger Ferocious, so I'll make adjustments that include Greenwarden of Murasa, Grove Rumbler (I'll get to him in a minute), and another Retreat to Kazandu.

Another point you bring to me is the unnessary effort for Woodland Wanderer through creature-only ramp with Beastcaller Savant, to the huge flaw that I did not catch with See the Unwritten. Sure he is a potential 6/6 with vigilance and trample, but he could just as easily potentially be a 2/2 as well! I believe either Grove Rumbler or even Zendikar Incarnate would be worthy replacements.

Now with your point about my splash of blue, let me tell you that I did have original intentions to adding in Kiora, Master of the Depths. The problem with her was that Beastcaller Savant and her did not interact well together and she's another four drop. Those issues really don't seem to be much of a problem if I simply cut out Woodland Wanderer and Beastcaller Savant, and add in Whisperer of the Wilds. Sure, it would be only Green mana, but taking in the previous issues into great consideration, Ferocious should trigger well if I make the appropriate adjustments. To add to the discussion of making blue better within the deck, Clash of Wills could seem appropriate for this deck when it will have a surplus of active lands in mid-late game. I didn't quite think of counters, but rather survival of my creatures (easy example of Whisperwood Elemental being protection against boardwipes).

As for your point about my landbase, I have 14 basic lands, and 14 cards that search for basic lands (including Evolving Wilds). I am skeptical about adding more non basic lands only because I do want to benefit from the cards that filter out the basic lands. This deck is casual standard, and with how games may go, I don't want to end up with an Explosive Vegetation while having no more basic lands to find due to Sword of the Animist. Now sure, my numbers are not the mathematic result of a perfect landbase around a deck with plenty of basic land searching, so my numbers may not be correct and I could possibly fit in more non basic lands. That is why I am skeptical.

You have made absolutely great suggestions, and I am very appriciative for them! Thank you.
