g/b scryb and force

This is the deck i am thinking about playing in standard. i think it is a good version of the deck but i haven't had a chance to play test much. feel free to let me know what you think. i am open to any suggestions. I switched in stupor over persecute because i vave a chance to play it second turn and i dont like the double black of persecute since i am only splashing black. I also added extirpate as a way to get rid of an annoying card. i took out the blanchwood armors to add giant solifuge main deck and added one more gaea's anthem.
