Hooked on the Brothas (EDH / Commander)

First of all, this deck is S L O W. It could probably use some more ramp, but I'm not sure how to make that work without the whole deck being a mess on account of the cuts that need to be made. Some more tutors would also be appreciated. Finally, I'd really love to focus more heavily on land destruction. I have an effective means of dealing with everything except planeswalkers and lands. I could probably scale back the nonbasics, but a lot of them offer a ton of utility. It's hard to make a 3 color deck work with Blood Moon, but I think it can happen. If I had a more effective means of handling ramp, that would be excellent. Alas, Mana Vortex/Breach and Restore Balance are outside the scope of this deck.

Living Plane, Karn, and Coating all allow me to interact with pernaments with which I have a hard time. Living Plane makes the deck extremely vulnerable to Elesh Norn and sweepers, but adding more artifact ramp could rectify that. Karn is probably too cute, but I like Coating a lot. The Abyss, Nettleblight, and Aether increase my focus on stax style resource denial. Tainted Aether is probably the best of them, but is a little dicey with Doubling Season or Parallel Lives. The other ones are very slow, but might still be worth while. Mikaeus allows me to reuse fodder for the Brothers and has great synergy with Karn and Plane. He's just so big and clunky. Worm Harvest seems very good. I will be replacing one of my 7 drops with it as soon as I figure out which one is under-performing.
