Houston, we have a broken Eldrazi manabase

I looked up all of the cards I could use in a purely colorless Eldrazi deck. Here is what I came up with for when I play Legacy again.

Here is the Eldrazi manabase I plan to use in Modern.

I think this manabase is way strong. With Thespian's Stage, we can have as many as 8 lands that tap for two colorless to use to cast Eldrazi, and when you get to seven lands, you are up to 12 with Shrine of the Forsaken Gods. This is a crazy-good manabase.

While on the subject of lands, I got these penny lands for Just for Fun play. These are the uncommon manlands from Ravnica block.
