This deck is very similar to the Colorless Eldrazi deck from Pro Tour Oath of the Gatewatch because it just tries to play all of the powerful Eldrazi creatures, including Matter Reshaper, Thought-Knot Seer, Reality Smasher, and Endbringer
The only setback being that eventually we will need our mana for the more expensive squirrel producers
It may not seem like much, but having a single card force a Wrath of God or hold back an early Red aggro start was a huge deal when Green decks were trying to beat Counterspell and Fact or Fiction
So you cannot use one creature to pay for multiple sacrifice costs at the same time, nor can you play an instant that your opponent has already forced you to discard to still gain its effect

You can also go out of your way to make a tap and untap engine capable of quickly stationing Dawnsire, Sunstar Dreadnought to 10+ charge counters and have it online
