This deck needs better mana fixing. I'd suggest 4 Underground River as a nice budget option. You can just take out 2 Island and 2 Swamp . If the deck still gets mana-screwed after that, you can throw in some Terramorphic Expanse or Evolving Wilds , since they cost nothing. I'd wait to put those two in though, since they make the land come into play tapped.

Awesome thanks! I was wondering that myself. I will try out your suggestion. Thanks!!

I would definitely go for 4x Mind Funeral and perhaps 3x Traumatize , for 3 mana a "4-land" mill will often hit above 8-12 cards, and will activate Duskmantle Guildmage 's primary ability cheaply. Again the same mage's ability will be an instant win condition if you drop Traumatize .
