It should be noted that Darwin Kastle´s version (the one shown here) is metagamed very heavily against control decks and might have unusually big (for the Rock) problems with aggressive decks like Sligh and Sucide.
If you want the deck to fare better against beatdown (not a bad idea after GP Reims where Sligh ran rampant) you should cut one Vampiric Tutor and 1-2 Cabal Therapies from the maindeck to add 1 Recurring Nightmare and at least one Spike Feeder or Ravenous Baloth.
Further lists can be found in the coverage for PT Houston or GP Reims on the
sideboard.
