I'll give Kelpie a shot, despite being skeptical. Dumb as it sounds, I'm generally trying to avoid a combo finish just to have some diversity in my decks (my other combo decks are faster anyway).

+1 Cabal Therapy (4)
-1 DR (3)
-1 Nether Shadow (3)
-1 Bloodghast (3) (unless there are other suggestions - may trim a flayer instead since this will churn through the deck quickly to find it)
+2 kelpie. (2)

Well see how that works. I don't have/run FOW so no need to keep the blue count up in the event it doesn't really work out. But, if it gets my bridges in the yard and more narcs in play, cabals to flashback for tokens, I'll be a happy dredger!
