Here is another of the deck building session I did late this afternoon. The Theros boosters were somewhat favorable this time, giving me two Mythic rare bombs to boot. I initially wanted it Red and Green (yes, I am now a fan) but the Green compo lacks good critters. Black, on the other hand, provided Gorgons to dominate the late game. 
Here is the deck I will play from the generated Theros card pool.
