Prodigal Pyromancer could be used for additional chance of getting your Mind Over Matter/Ophidian Eye or Curiosity combo. Also, just would like to point out that High Tide/Palinchron will also give you infinite mana until EOT. Laboratory Maniac might be fun because of control and draw, and Niv-Mizzet, the Firemind or Azami, Lady of Scrolls/Mind Over Matter combo. I love the deck! +1
You might wanna put in Sphinx of Uthuun and/or Fact or Fiction.
