MB:
Remove 2 Crypt Incursion
Add 2 Darkslick Shores, maybe some other land but 23 lands is ideal. Ooo try an academy ruins if you have one. 


SB:
I actually love the Stony Silence, but I might run 3.
I'd consider cutting the Profane Memento since the Leylines of Sanctity are there.
Rest in Peace can go.
So can mind funeral. 
I think it should look like this:
4 Leyline of Sanctity
2 Leyline of the Void
3 Stony Silence
2 Surgical Extraction
2 Crypt Incursion
2 (Either Darkblast if you can find them or Disfigure)
