jchudz - I actually haven't had any issues casting Grasp of Darkness since the mana base is so fluid.

Why did you take out arlinn?

Don't have much time, so here's a quick (not meant to be offensive) review on my opinions; I'll explain later:

Ultimate Price beats Grasp of Darkness

Kindly Stranger  ^Flip might beat To the Slaughter

Vessel of Nascency usually fits better than Traverse the Ulvenwald

Get the mana base as close to lined up with mana costs as possible.

Drop a single land; it statistically guarantees 4 lands at turn 4 draw, and you have digging to round it out.

Looks pretty solid, gonna try and definitely build something similar to this. I dig the silver bullet copies of Nissa and Atarka to tutor from Traverse. Thoughts on Sin Prodder? Anyways +1
