One thing that really stood out to me was that the average CMC is ~4, and there are only 4 ramp cards. That's higher than my Omnath, Locus of Rage deck and it has plenty of high-CMC bombs!

There aren't too many options for ramp in BW, but you'll find plenty of ramp in black. Urborg, Tomb of Yawgmoth and Cabal Coffers go together amazingly. Basalt Monolith is a nice, quick 3 mana. Orzhov Cluestone, Commander's Sphere, Mind Stone and Hedron Archive all provide ramp early game, and can be cracked for draws late game.

As for cuts, I'd recommend Vizkopa Confessor and Sin Collector since single player discard is low-impact in multiplayer games. Agent of Masks, Yahenni, and Revenant Patriarch are either mediocre or don't really follow the deck's game plan.

Hope this helps!

Triton,

First off, nice to see you again. Second, I figured I would have to address all these issues again. I know that the CMC is heavy, it was before I had to rebuild the deck. I totally forgot about Urborg, Tomb of Yawgmoth so that will be something to go in. If somebody is giving me trouble then Vizkopa Confessor and Sin Collector can take care of some of their key cards (looking at you combo and control players). Revenant Patriarch may seem underwhelming, but it has really helped me before. Once when I used it against an Aurelia, the Warleader voltron deck I was able to buy some time so I could ult my Liliana Vess to take them out. Agent of Masks and Yahenni, Undying Partisan seem underwhelming, but they work great with the other cards in the deck.

Thanks for the help!
