As far as the exact changes i would suggest.Main:

-1 Outpost Siege Wonderful win con but i feel like its the weakest of all of them. Its khans ability is great but you could be doing more with the insaine amount of mana you generate with this deck when youre not going off. I think Ant Queen is a better mana sink and win con

-1 Temur Sabertooth Really like the inclusion of this card. Think it gives you a wonderful late game but for a 4 drop seems situational. Thats why my thought is to move it over to the sideboard.

-1 Forest You have know the mana base way better than me. 4 instead of 5 lands may hurt the fetch lands to much but i was just trying to find room for the Forbidden Orchard

+1/2? Intruder Alarm Another source of an infinite combo which can be done without Cloudstone Curio. Right now pretty much all of your infinite combos require Cloudstone Curio which may be a point of failure so i would try to create a few more threats for the opponent. I know you can win without Cloudstone Curio but Intruder Alarm feels like it goes so well with it.

+1 Ant Queen A replacement win con for Outpost Siege. Feel like it has more synergy with both Intruder Alarm and Cloudstone Curio

+1 Forbidden Orchard Mana fixing and a good combo with Intruder Alarm after a big Genesis Wave. Just feels like any deck with Intruder Alarm should have at least 1 of these.

Sideboard:-1 Joraga Warcaller As i mentioned in my previous comment I think you have plenty of win con's as it is unless im missing something with Joraga Warcaller. Wouldnt bring Ezuri, Renegade Leader in over him pretty much any time I needed a effect like that.

+1 Temur Sabertooth Amazing card for late slower games as well as plenty of protection for your other guys and a wonderful combo enabler.

Its possible that these replacements may make you weaker than you like late game because that is where Temur Sabertooth and Outpost Siege shine and may not be the correct replacements for these cards but think it should be a consideration. Yet again love the deck and will probably play it in paper for a while.

All of your suggestions are extremely sound simoHayha...the toughest part about discussing this deck (and one that you hit on the head!) is that it takes a few dozen rounds to really get good with the deck (as you draw so much that often times you have to look ahead). I do appreciate the kind words, as you are right that often the most difficult decks to "see" are generally the ones that end up playing well (because once you have a good grasp on it you can be sure the opponent won't know what's coming :) )

I have loved Intruder Alarm elves in the past. You are absolutely right that the inclusion of Intruder Alarm would also ensure that you would want one or both of Dryad Arbor and/or Forbidden Orchard (such great synergy there).

And you are right about Outpost Siege. It is the weakest of the win-cons. I initially played it because it plays "through" some of the good hate cards against us (both Torpor Orb and Eidolon of the Great Revel...but really that most likely means it should be in the board rather than the main. I actually had recently replaced it with Eidolon of Blossoms for a "test period" (I like to try out ideas for a small period of time before I make any changes on tapped out or MTG Salvations..) as it is a ridiculous card-draw engine in any deck playing Utopia Sprawl, Abundant Growth, and a god or two :)

I will absolutely, however, try out Intruder Alarm as well. You are right that many of the combo's rely on Cloudstone Curio so having an additional means for "infinite" combos would be nice. I was utlizing Freed from the Real as it actually has a turn two infinite combo with Arbor Elf and Utopia Sprawl (with those two and two Forests you actually have infinite mana...and with the right hand can "go off" as early as turn 2...but I'm rarely fond of cards that don't really have synergy with anything else in the deck (no matter how fast they may be). I went ahead and made another deck with this combo that includes Bloom Tender and Elvish Archdruid (for additional synergy) but that is another deck altogether (it's an Elf Aggro deck.)

I will try out Intruder Alarm in my next testing session and see if and how I can add it in here. I appreciate your help! Hopefully it becomes a future competitive option for Elf players in Modern!

Thanks for the response and you're probably right. Prehaps Seige should be the sideboard card instead of Temur Sabertooth mainly for the devotion side of things. Good luck on your testing! I feel this build or a build very close to this is already a competitor in modern . Good work.

First of all, I love your brews, and have been playing Green Devotion / Nykthos decks for over a year because of you. So thanks for finding ways to make cool cards work well together.

Secondly, have you considered Impact Tremors in this deck as another alternative to Purphoros, God of the Forge or Outpost Siege? I think it could work well with all the bounce as it is much cheaper and does basically the same thing as the others (enter vs exit notwithstanding).

Thanks so much robrone9! That means a lot to me truly...

I did see Impact Tremors and certainly need to try it out. It did get me thinking of ways to utilize the card (as 2-CMC and as an enchantment is a big deal). I played around with another green devotion deck that was non-elves (as you can go infinite with Impact Tremors, Cloudstone Curio, and two copies of Burning-Tree Emissary...) It is ceratinly a great idea to try out given its lower cost!! Thanks for the great idea. I'd love to see your devotion decks!

Btw...sorry for the delayed response...we had a little cancer issue we had to get through. Not to worry though. All is well now!

! Amazing work man..I been looking for an elf deck and this fits very well.. I want ask you somethings..now the metagame have eldrazis, melira(abzan, kiki variations), affinity, infect and some wacky control like lantern control... you could see collected company as an addition...and which sideboard options you consider/add to the metagame right now april 2016...I appreciate your time and support .. thanks man.

Sorry to all who have posted. We were away for quite a bit (father passing, one "bro" having surgery, etc.) We will update our lists and try to answer everything possible ASAP.

What would you do to reduce the price of the deck? Obviously core cards like Ezuri, Renegade Leader and Cloudstone Curio can't really be replaced alongside Garruk Wildspeaker , but what would you cut to reduce the price?

Are you still working on this deck? I’m going to GP Vegas and was wondering if you think this deck can hang with the post-Hoogak meta: Humans, Phoenix, UW Control, Tron, and Dredge? I love playing Beast Whisperer Elves but I’m not confident in my Phoenix and Dredge match up. Would this be an improvement?
