Side board Apostle's Blessing . Drop Mindshrieker completely. Drop Mystic Speculation . Add two more Mind Grind . 4 Increasing Confusion . 4 Psychic Drain . Once you get your mana combo going you will need one of these cards & you having it in hand, It's game by turn 4. Apostle's Blessing is very good sideboard. The game will be over b4 Mindshrieker has to really do anything. Mystic Speculation is good, but you have Duress and Gitaxian Probe which are both better turn ones then scrying. That's what I changed on it. Great deck!

Thanks for suggestions, BattleMasterBill: I am going to think about these changes. Apostle's Blessing is very good for defence but often I use it to make a creature unblockable in order to trigger the duskcrank combo. That's also why I have two Mindshrieker instead of Mind Grind . Sorceries are good but, without an infinite mana source, almost useless. I'd rather use Blue Sun's Zenith because it can be cast during the combat phase. You're right about Mystic Speculation , in fact I often use it in combo with Gitaxian Probe .

If you are looking for a trigger for that combo here is a much simpler way. Thought Scour . It can help with draws & it can trigger your combo!

Have you thought of Serum Visions or Peer Through Depths?

I thought of Serum Visions instead of Mystic Speculation. I kept the latter only because it can be used as a tutor if I have my infinite mana combo off and nothing to use it with. I also feel that Taigam's Scheming would be better for my deck than Peer Through Depths but I still don't know because on turn two I would ideally like to play the first card of my combo. Thanks though

AEther Vial is also good in this. I do like Taigam's Scheming too I think it gets there.
