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)
