I can say just by only reading the Planeswalker, who ever goes against this deck, will die very soon.
w00t another Ezuri EDH, I have one too :-)
http://tappedout.net/mtg-decks/elf-ball-now-in-edh/ if you need ideas. Good luck with the deck although I warn you people tend not to like you when you can kill a player a turn via overrunning...
Nice! I have an elf EDH too using Nath of the Gilt-Leaf as a commander... LOVE it! A couple of ideas: Immaculate Magistrate + Joraga Warcaller works a lot like a Coat of Arms . I found that I liked Viridian Shaman more than Viridian Zealot , especially with a Wirewood Symbiote out in play to use it over and over. Also, I found also that my power increased a lot when I added Quest for Renewal for the untap mechanics. one use of Nullmage Shepherd activates it, and then my opponents are loosing an artifact and enchantment during each of their turns... so that was fun. Love the deck! let me know what you think of mine! (Nath's Wrath)
I suggest adding Primitive Etchings to this deck, it's really good card draw.
