Pretty neat! Playtested a little, and it works great.

Quicklings might be cool. To be tested.

I would try keeping Courser of Kruphix and give him some friends. It deserves a good spot in your deck, especially considering how you really need to drop a land every turn. Plus, it provides some lifegain (2 for Evolving Wilds!), which buys you time to play and replay your Twingroves.

Fun to play! +1

Oh! And I'm not entirely sure about the full playset of Curse of the Swine. Maybe 3 would be enough (you don't want to draw them one after the other...), and you may add some return-to-your-hand stuff. I'm thinking Force Away, which would get you some hand fixing with your fatties, or Voyage's End for scrying.

Could also add Battlefield Thaumaturges to diminish the Curse's cost to UU, and Sea God's Revenge to remove 3 tokens for a mere 2U. But that's just a completely different idea.

Thanks Lightcarrier. Your probably right about Courser of Kruphix. I've always had a sort of illogical resentment to that card and Sylvan Caryatid just because everyone plays them and they're so expensive. So far with this deck I've had no shortage of land, but there are many benefits to drawing more. Not just boosting the Kalonian Twingrove but every land drawn from the deck, after shuffling improves the odds of finding better creatures with Genesis Hydra Dig Through Time Nessian Game Warden. I could probably even reliably play Archetype of Endurance.

About Curse of the Swine I really like this card here, I want to be able to play it early to remove 1 or 2 threats and count on drawing another for latter. I find it so versatile and devastating. It's my main defense against flyers and only answer to Gods, indestructables, or any creature with powerful abilities.
