First post here :p Hellllloooo all !
It's interesting, because I just started testing some B/G Aggro/Disruption deck, which as a lot of similar cards.
My current decklist (keep in mind I'm still testing, this is why I have 1-ofs, I want to feel if they are good or not):
// Lands
  1 Strip Mine
  9 Swamp
  1 Forest
  2 Overgrown Tomb
  4 Bayou
// Creatures
  3 Nantuko Shade
  3 Withered Wretch
  4 Dark Confidant
  3 Skyshroud Elite
  3 Hypnotic Specter
// Spells
  4 Null Rod
  4 Duress
  3 Cabal Therapy
  4 Dark Ritual
  4 Land Grant
  4 Root Maze
  1 Chains of Mephistopheles
  1 Demonic Tutor
  1 Choke
  1 Rancor
// Sideboard
SB: 1 Null Rod
SB: 1 Choke
SB: 3 Chalice of the Void
SB: 4 Diabolic Edict
SB: 2 Umezawa's Jitte
SB: 4 Naturalize
I play a green splash for ROOT MAZE, which I find is really good:
-with it, fetches need 2 turns before producing mana (this is the reason why I play Land Grant instead of fetches myself... but it might not be the best choice, because it reveals my hand)
-it slows down decks like slaver/combo
-tendril combo has a harder time comboing off without artifacts (and they can't just EOT rebuild it, because it is an enchantment

).
I play the Overgrown Tomb because it is good, and if you have Root Maze in play, you don't care about the drawback.
This deck is quite good against combo, because of the discard, the Wretch (good against Yawg Will), the Root Maze, the Null Rod... (combo has a hard time comboing of with Root Maze + Null Rod in play.. of course they can try the Cabal Ritual plan, but it is still hard).
Against stax, the Wretch is great against welders. Moreover, I think Rancor can be good against Smokestack, because it gives one permanent every turn.. Finally, we have lots of basic lands, which makes a Wasteland + Crucible lock harder for them.
Things like Tormod Crypt or Jester Cap do nothing against this deck.
Against Ichorid, we have Wretch and creatures to block.
Against Control, we have a lot of discard, Confidants, Root Maze + Null Rod + Choke to own their manabases, and some really effective beaters (if they let a Nantuko Shade hit play, they are dead in a few turn).
Right now I am testing Rancor, Chain of Mephistopheles, and maindeck Choke. Choke is great in today's metagame, where blue is very often played.
I'm not sure about the Skyshroud Elites, because even though it does apply early pressure, it has no other ability. I'm also not sure with the SB Jitte, I think it is good against random aggro decks, though...
We might also need to use maindeck Diabolic Edict, to counter Tinker->Colossus.
Thoughts?
