I became interested in this deck recently. I've actually long dismissed most lists I've seen as being too Glimpse-reliant, but I felt that the 4 Priest/4 Archdruid list David Vo got 4th with recently at Atlanta had a lot of potential. The biggest problem I had with this list was that it didn't run Living Wish.
Living Wish is, put simply, retarded in Elves, and it's not worth any sideboard conversion to not run the card, because any strategy that nukes you is going to do so unless you're allowed to swap out 30-40 cards anyway. But Living Wish means always having a Gaea's Cradle or Emrakul available when you need it and never otherwise, as well as the pieces of the combo and answers to various problems and decks like Bojuka Bog and Phyrexian Revoker. More importantly, with or without a Glimpse you can often cast Emrakul as soon as you hit 15+ mana, which is very easy to do if you don't hit significant creature removal.
Green Sun's Zenith I eventually just built up to a 4-of because it was that good, and at that point I cut Summoner's Pact. The entire point of this list is to be able to win without Glimpse. Glimpse or no Glimpse, this deck will generally kill you on turn 3 about 80% of the time if there's no disruption, and its multiple paths to victory mean that you really need multiple points of disruption to have a good chance. Without Pact, Glimpse can even be used just to set you up on turn 2 or 3 for a next turn kill; first turn Llanowar, second turn Glimpse, Quirion, two other dorks, maybe a Heritage and drop a Priest, pass the turn, is actually a very strong play.
Of course, at the end of the day it is still elves. If someone's running StP, Lightning Bolt, Force, Daze, Counterbalance and Firespout all in the same deck, you're probably not going to win. But against most of the field I think this list is ridiculously strong and fast.
As a last point, I'm running Kamahl over Ezuri since;
1) It's slightly easier to kill people with a moderate amount of mana + Kamahl than with Ezuri, since in the scenario where, say, you have two priests and a Ranger + Kamahl, you can turn your lands into creatures to get additional bodies out there; an important part of optimizing the deck is knowing when to try and combo, and when you should just fucking go and kill them with your dorks,and
2) It's slightly better removal protection; Ezuri is only effective against Firespout, Deed and EE, whereas Kamahl can turn Damnation or Wrath into a gamebreaker by nuking the opponent's mana base. You really don't need much left in hand to take out a dude without lands.
Of course, Ezuri isn't an impediment when Glimpsing off, so I'm not 100% that this is the optimal choice, although Kamahl is much more badass imo.

the SB is slightly less polished; four or five slots are still questionable. Otherwise I've been very pleased with the results I've been getting testing this list.
