Scapeshift also seems good in a deck like this. Sacrifice a number of legendary lands to fetch more legendary lands. Then use Kethis, the Hidden Hand to play a lot of them back after casting Azusa and Gitrog from the yard.
Even just playing 3 lands a turn after milling myself seems good.
The first thing I added was:
I built a list on Manastack and also had Oracle of Mul Daya, Ramunap Excavator, Wayword Swordtooth, Courser of Kruphix, Hermit Druid, and Exploration. Hermit Druid with any number of these, lets me just dump tons of lands into play.

I didn't list Fastbond because I don't have one.
