[Casual] B/Blk Rogue Unbockable WIP

[SiriusGrief]

B/Blk Rogue Untargetable

Constant player/creature damage that opponent cannot block. Punishing opponent for attacking/tapping creatures or lands.

(Opinions/suggestions and questions are welcomed.)

I like the concept.

I would get rid of all the creatures that have a conditional "can't be blocked" like intimidate, landwalk, skulk.  And then all those cards dealing with changing land types should go too.
Stick with just creatures that can never be blocked.  And then pump those creatures and give them lifelink.  Slither Blade should be in the main.
I like Mark of the Vampire.  Maybe some Cartouche of Ambition as well.
I like Sinister Posession and Sensory Deprivation for removal of small creatures.  Maybe some Murder to deal with larger creatures.
I suggest more counterspell, maybe Essence Scatter and/or Mana Leak.

Happy Brewing

I think a card like Ninja of the Deep Hours would do wonders for this deck.
