The so called "Dimir" guild cipher mechanic and some milling.

Cool. Some neat stuff in gatecrash.

You could swap out a land or two for some more mill boosted cards, such as wight of precinct six, or a consuming abhorition.
I was looking for mill boosted things initially but I opted out of the Consuming Aberration because he costs 3UB and at that point I was watching the mana curve closely. I may get some to swap in after testing the deck first. And the Wight is a great card except for the fact that it only gets boosted by creatures in the graveyard, and with my luck the opponent would be milling everything but. Regardless, that is some good advice and I may add both after testing it.
