Anyone Cubed Eldrazi Monument?

Hello all,

I've been considering adding \[\[Eldrazi Monument\]\] to my cube as I like the combination of buff, evasion, and protection but am wondering if the high CMC and mandatory sacrifice are too much of a drawback to make playing it worthwhile. I'm having trouble evaluating it so I thought I'd ask if anyone here has tried playing with it and what were your experiences?

Thanks!
