First, I forgot to mention that I took out one Doom Blade and one Liliana's Caress for two Distresses.
Next, I added into the maybeboard three lands. As of now, the deck contains only basic swamps, but I am considering spending some money on the Shizo, Death's Storehouse and Urborg, Tomb of Yawgmoth. My main dilema is that I do not know how many to run, and while one of each is no problem, running a playset of each will get expensive, and I don't know what the happy-medium is. Bojuka Bog is another consideration because it is basically just a swamp that removes the opponent's graveyard, but I don't know if I really need it or not. It is cheap enough to run a playset easily, though, but I just don't know if it's necessary.
