Please don't follow Reid down the Pox rabbit hole.
That's not my intent.
My thinking is that Sinkhole + Hymn + Edicts + Liliana is powerful. I was already thinking of this before Reid came out with that deck (I think some past posts on here would back that up) and I'm a little miffed that he kind of got there before me, though he is a pro lol
The build I originally wanted to do would play those cards, and then play Chalice of the Void to lock out 1CC cards, with my deck not playing any 1CC cards. I still like the idea... but I don't know if I can decline to play Thoughtseize/Inquisition and keep up.
I like the idea of Monoblack for the consistent mana base, and the lack of a need to play duals+fetches. However, blue offers a lot to a deck like this. Also green does too, if I wanted Shaman+Decay. I just want something consistent, disruptive and powerful.
