Oloro, Guardian of Esper (EDH / Commander) [Revisión 11]

I wanted this to be mono_sphinxes.dec but there aren't enough good ones to fill out a commander deck. This is what I've ended up with so far. The mana base is still the biggest issue I'm having with this. I think 36 lands is still a bit on the low end.

9/27/17:
-Isochron Scepter
-Archmage Ascension
+Unesh, Criosphinx Soverign
+Argent Sphinx

Really don't have a ton of targets for Scepter. Love the card but it doesn't fit in this deck. With Jace I basically have Brainstorm on a stick already.
Archmage Ascension works well with Oloro (when you draw it) but I'd like to lower my creature curve and a 4 drop that doesn't die to removal fills a good gap.

6/21/17 Update:
-Chromatic Lantern
-Everflowing Chalice
-Vedalken Orrery
-Thopter Spy Network

+Wasteland
+Sensei's Divining Top
+Mystical Tutor
+Wrath of God

Lantern not needed anymore since adding Celestial Dawn. Chalice is nice but without proliferate triggers it has a set (usually low) potential.
Orrery is nice but I'm opting to swap in less edge-case useful cards like a tutor and board wipe.
Removing Thopter Spy Network because we already have Sharding Sphinx and I'm trying to keep in the tribal flavor. There's not a 100% overlap between the two cards but the thopter tokens aren't incredible important in the grand scheme of things.

7/1/16 Update:

• 1 Island

• 1 Sunken Hollow

• Temple of the False God

• Mana Crypt

• Unwinding Clock

• Darksteel Forge

• Filigree Angel

• Astral Cornucopia
  A long time ago this deck was more artifact-focused but it no longer has use for some of those cards.

• Ixidron
  I found that Ixidron would normally end up working against me more than for me. Comboing with Elesh Norn is a nice board wipe but on its own it's lackluster.

• Windreader Sphinx

• Sphinx of the Final Word

• Sharding Sphinx
  Adding some new spinxes and and old ones back in.

• Jace, the Mind Sculptor
  I recently acquired Jace and a Mana Crypt from Eternal Masters so why not add them in?

• Sire of Stagnation
  I got excited when I saw this card spoiled in BFZ. I finally picked up a copy for just $1 and I'm hoping it makes a great addition to the mill subtheme in the deck.
