I really like this card, but 4 cmc is a real concern. I could see a BUG type deck with a draw engine like:
2 Rashmi, Eternities Crafter
2 Sylvan Library
1 Sensei's Divining Top
1 Jace, the Mind Sculptor
2 Leovold, Emissary of Trest, though it's not really a draw engine.
And perhaps Jace, Vryn's Prodigy and/or Snapcaster Mage as well.
But Jace might just be better.
