I think you could replace a lot of your tapped alnds with their guildgate counterparts, i.e. Timber Gorge could become Gruul Guildgate. It means you can then include and get extra value out of Circuitous Route for fixing. Plus if you ran all 10 you could find a spot for Maze's End :P

I have also been impressed with Retreat to Emeria as a card in Tazri ally builds.

enpc Man, you are right! It's like run a Skyshroud Claim with shocklands. This Maze's End is dirty, I kinda liked. :P

I think I'm gonna cut Immortal Servitude that is underperforming and put Retreat.

Thank you very much.

The change looks good. I think you could also replace Wood Elves with Rampant Growth since you're not running any shocklands, which is where wood elves excels. Also, is there any reason you're not sporting Sol Ring? Just to keep the cost down? Also, Avacyn's Pilgrim and Elves of Deep Shadow can be good early game fixing/ramp.

I would recommend finding some space for Kalastria Healer. This is the main win conditon of combo Tazri lists but is also just good when you're spewing creature into play. Especially with cards like Brago. If you wanted to long term as well you could include a Peregrine Drake and either Deadeye Navigator or Eldrazi Displacer or Archaeomancer (who pairs with Ghostly Flicker) to give you another infinite combo line.

enpc The main reason for the lack of the cards you listed is to keep the price budget, with the exception of the Kalastria Healer, this one I have no reason and I'm going to put on the list.

About combos, I prefer to stay away from this dark zone :)

@enpc The reason about the Wood Elves is the blink effects with Brago, King Eternal and Zada, Hedron Grinder, but looking with your eyes I thinks it's better substitute for Wild Wanderer
