I'd suggest modifying the file a bit if you haven't already. One of the problems I found was that all the major units are Rng 1 (not so much XXXX, as his ability isn't restricted by range), so if you manage to build up a momentum, you can't actually play all your units until something else dies. Some good cards to put in that fit the theme would be Dragon of the Mercurial Night, Dagon, or Joachim. Some of these might be a bit hard to get a hold of, but they're worth the effort if you can manage it.
I also took out my Ancient Zombie lord for a second Shade, as double shade can wreck the flow of a Cath>Owl Sage opening, and generally shade is a brilliant card.
the 2nd and 4th SS could also do with a change, people commonly iczer into 2LP SS thanks to Mitzett, and Death Knight probably isn't as strong as Dub or Mitzette anyway, and if you think you can control your opening enough, changing MD Support for a Priestess of Madness can give you a bit more flexibility in your early game.
[shameless link] I can still claim I'm a free player cause I haven't spent any of my
money on the game, but instead I used Prizerebel to get my EX packs. Gran Train = viewtopic.php?f=13&t=11761
