If you are worried about getting black mana you could always use a few more fetches and less Islands, or use those Ravnica Underground Seas (Watery Grave). I like this deck, I used to use it back in the day. My build was Mono Black because I was too dumb to play Blue, so I chose to use things like Nantuko Shade and Hyppies.
I see a ton of Aggro, so I feel that this deck is worth playing again, the only thing I would change in this meta is 4x Ensnaring Bridge.
Was that serious or just mocking me?

It sounded serious until you mentioned having 4x Ensnaring Bridge. By the way, I'm fine for black mana, I've not had any problems yet.
well i would wait to Pump my Shades after I declared them as attackers, so as xycsoscyx said, I only needed to keep two cards at hand each turn, which isnt hard. I dont think I used 4 Bridges, but I do remember using 2-3 because they shut off my friends with their wierd Stompy decks that relied on Silvos, Rogue Elemental to win. I tried this list again for like 5 games on MWS and I realized I dont really like it, it's just too different from every other deck I play.
I dont think cutting blue would be bad because not only will it give you a more stable mana base but it will allow you to use Chains of Mephistopheles. The card annoys control players out of their minds from my experience. Besides, the only blue you use is like Ancestral, Bstorm, and Mana Leaks.
