Modern Eldrazi Brew

[Forbidyourways]

I wanted to ask what you guys think about splashing green in the new Mono Black Eldrazi going around. Have the green for  {Ancient Stirrings} to dig for the pieces you need and  {World Breaker} the Reach is great cause this deck is weak against flyers and the cast trigger isn't terrible helps the processing and if they do kill it you have a way to get it back also can have  {Abrupt Decay} in sideboard so what do you guys think?
