I do like the idea of the Sphinx! I wanted to go Eldrazi's just for some added fun. I know it will take an extra turn to use them but at the same time since they're soooo big even if I am able to drop one let alone two or three then I am going to be putting a hurt on someone lol.
I am still working on this deck as I have every card basically other than the Eldrazi's. Gotta fix up some lands and get it down then to 100.
