What about Coat of Arms? It could basically break the other player if you have enough elfs out.

I play against a very mean Krenko goblin tribal most of the time. He doesn't even like to play that two edged sword. I liked it and originally had mine in. It was awesome when i already had the advantage....but against other tribal it can decimate the player and honestly has no ue otherwise. It's always fun in pod though :) I have tended to play more one on one recently.

Well, as a less dangerous choice, how about Voice of the Woods? If you have so many elves, making a 7/7 trample isn't the worst thing you could do.

Very true. I have a hard time even with the protection i have, with avoiding board wipes. Eldrazi Monument is the plan when i can get it....and i had Soul of New Phyrexia meantime. Soul just wasn't as useful as making my land drops more consistent. Having five creatures for one big one is possible, but doesn't seem too likely for me in any consistent manner. My most common win con is ridiculous mana 3 or four elves and Ezuri, pump into him. Game. I have also Considered Omnath, Locus of Mana. I think he would really benefit my build. Removing cards however is another story.....

What about Skyshroud Claim, Nature's Lore, Kodama's Reach, Land Grant, or anything of that ilk? Does that make it too slow for wasting a turn for getting mana? Also as psudeo-removal, how about Lignify?

I love Land Grant, and i had forgotten about Lignify. I really like that, very my style will have to figure a way to get those and put them in. The others are good...but it was hard enough to fit in Sylvan Ranger and Farhaven Elf....and they are elves :)

Missing a bunch of cards:

Umbral Mantle is cheaper mana-wise than Sword of the Paruns to get infinite mana if you are only going to run one. I run both and Staff of Domination.

Big mana creatures that are missing: Wirewood Channeler, Karametra's Acolyte (not an elf, I know, but making infinite mana gives her a pass), and Viridian Joiner.

Maze of Ith coupled with Argothian Elder will give you infinite mana during your attack step (which is when you really need it).

Illusionist's Bracers coupled with Seeker of Skybreak and any mana elf gives infinite mana. If you get the bracers before finding Seeker, doubling up Ezuri activations is always good. They also create infinite mana with Argothian Elder and Wirewood Lodge, allowing Elder to untap 4 lands.

Kamahl, Fist of Krosa can be a backup to Ezuri, wrath protection (go ahead and wrath, in response I make all of your lands 1/1 creatures!), and another way to make infinite mana by animating Nykthos so you can stick Umbral Mantle/Sword of the Paruns on it.

Fierce Empath + Craterhoof Behemoth - Secondary win condition

Ring of Three Wishes / Planar Portal - Yes they are expensive in terms of mana use. You are playing Elves. You can afford it. They find your combo pieces.

Soul of the Harvest - HUGE turns as you play Elf after Elf. With Cream of the Crop, you would have to be unlucky not to play every elf in your deck.

Cauldron of Souls + Melira, Sylvok Outcast - wrath protection

Cloudstone Curio + Big mana elves and haste granter = infinite mana If you add Aluren, you can do it with any two mana elves costing 3 CMC or less.

Copperhorn Scout - allows you to tap attacking elves for more mana to feed into Ezuri

Since I have recommended a lot cards, here is some of what I would cut:

Nissa's Chosen - Not very good as a singleton

Nissa Revane - Not very good without 4 Chosen and lifegain is subpar in EDH(you still die to 21 Commander damage)

Steely Resolve - Can't use Ezuri's regeneration ability with this out or equip your equipment

Elfhame Sanctuary - You should not be skipping draws for land. A proper Elf deck can run on 2-3 lands in play

Talara's Battalion - Just a big, dumb beater. Once you get infinite mana, ALL of your elves are big, trampling creatures.

Realm Seekers - See Elfhame Sanctuary and Talara's Battallion

Nissa, Worldwaker - Elementals are not Elves and are not pumped by Ezuri. Also, opens your land up to destruction by creature removal. Untapping Forests is ok, but would be better if she untapped Elves. You will never get her ultimate.

Also.... if you want to be "That Guy", you can include Winter Orb and/or Storm Cauldron. Neither should slow you down much as your guys are cheap and make their own mana.

Thanks so much for the suggestions! have been looking for an Umbral Mantle for awhile also the Staff of domination. I really like that go ahead and wrath Kamahl and will try and get a hold of him as well. Illusionists bracers and Rings of Brighthearth have been on my list for awhile. i already have a Soul of the Harvest, copperhorn scout, fierce empath, and a Craterhoof Behemoth. Copperhorn, Soul and Behemoth were cut out actually. Copper horn tended to die too easily in my playgroup, Behemoth rarely showed up when he'd be of use, and i don't think i ever really gave Soul of the harvest a chance. Also you certainly justified a lot of those cuts and i will consider them as i move forward with this deck. It'll be hard top see some go, as Elfhame Sanctuary has recovered near unplayable games for me and Realmseekers, when they are used, have always been a game changer. The Nissas are more personal choice and flavor then all too practical i see now, but i still love em. Didn't even know of that Maze of ith, Argothian Elder combo. gonna try and get the Copperhorn back in tonight. Thanks so much Gavvin.

Here is what I am running currently. Wins quite a few games.
