I think for Modern you're way too creature heavy and too light on control. I would take a look at some Inquisition of Kozileks or Thoughtseizes as a t1 play. I've been working with this deck: Mono Black Devotion and it's been playing great.

Ideally with mono black you're looking at something like this:t1 - land + hand disruption t2 - land + relentless or spot removal t3 - land + gatekeeper, arena, lili or geralfst4 - land + oblit or board wipe if they're going super wide earlythen from then on you can keep on controlling with lili/removal/gatekeepers etc. and keep the pressure on with geralfs/relentless/oblit etc until you eventually drop a gary.

I'm a fan of the build in general, just seems like it may take a bit of tweaking to get it competitive.

retropman Thanks for the comment. I definitely need a solid T1 spell. I prefer Blackmail over Thoughtseize in a lot of matchups as I don't need to shock myself for it and as an added bonus I can hit their lands. This is my 8-RACK ATTACK deck that worked pretty well without Thoughtseize main board. I'll try one or both maybe with Surgical Extraction for a bigger hit.
