So I as well have been playing Elves, basically since I really got in to MtG (about the release of RtR, so not terribly long).

There is an infinite mana loop w/ Ezuri, Renegade Leader and Devoted Druid x2 given you can get 5 mana total into Ezuri without killing either elf (So basically you have 3 mana of some kind plus the 2 Druids), Ezuri gives them +3/+3 each, making it so they can tap for a total of 6 mana, dump 5 of that in to Ezuri and have a net-gain of 1 G, rinse and repeat until all your creatures are infinitely strong (with trample) except for the two druid (which die after end phase, but you pretty much are banking on winning w/ infinite mana).

It's not out yet, but a card I would like to try in my Elves (I DO have Collected Company, which I got on Khans Release for like $2 paper) is the new 2 drop that nets a token as well - Dwynen's Elite. This card, paired with Heritage druid, should net some serious tempo since you get a bear +1 and can tap for 3 more that turn with only one more card (Instead of the normal double dorks).

I would probably take out a couple of dorks for this and with your build put in at least one other Ezuri in you build.

Also a note, I believe the Elite goes infinite with Cloudstone Curio + Nettle Sentinel +Heritage Druid (the druid just has to be on board for the Tap 3 for GGG). Netting you infinite mana and infinite ETB (Essence warden? Or for those who play the U/G edition for Beck.

Note: Didn't see you having Dwynen's Elite until after - however what I said still holds true.

Only problem I see so far is that we're pretty weak to removal early that will set up back a lot, and our combos rely on a lot of pieces, that can be relatively tricky to not get out. If people can afford CoCo, I would probably recommend it in this version over Chord of Calling.

Anyways, that's my piece.

Additional note I also forgot to add in my long-winded comment, genesis wave would also be a decent replacement for Chord of Calling as well. Since then you can go off with the infinite combos a bit more frequently.

Anyone playing Combo Elves deserves a +1 in my book!!! We Elves players got to stick together :) +1 of course.

so im kinda obsessed with this deck right now, and i just say the spoiler for Rhonas's monument i think it would be perfect in this deck

Have you been accounting for summon sickness in your combos?

KumaLKS yes, most of the combos are based on etbs, infinite damage on turn two requires a Nettle Sentinel turn one (so it doesn't have summoning sickness.)
