Grixis with Dimir Emphasis deck online

I bought one Nicol Bolas, Planeswalker and two M13 Jaces from the bots, and came up with a fun Grixis deck with blue black (or Dimir) emphasis. This is a simple deck that does not use the more complex multicolored Izzet and Rakdos cards in RTR because the only dual land playset I have is for Dimir.

Here it is.

 

Here is the sideboard.
