If you cut Belchers from the lists with Land Grant then you may as well cut Land Grant and play Fetchlands so they can't see your hand and then counter your land drops.

If you want to play the mono black version of this deck, just play with the robots, Vault of Secrets and Mox Opal to max out on all of the fast mana or Swamps and Kobolds so you can build up a wasteland proof manabase and feed your dead cards to Chrome Mox.
