The current Shadow Priest list I'm running. Illucia is in here simply to disrupt combos - the payoff is incredibly worth it. 

I wasn't a fan of the list using Elven Archer; found that to be wholly unnecessary - the deck can push enough damage with Void Shard and Knife Vendor in my opinion. I also found that Cheesemonger is my new favorite card in this meta. You'll often be running short of cards in your hand, and this guy is fantastic at filling it back up, especially against Rogue, Mage, and Warlock who will likely be forced to use spells to remove it. 

Against Mage, basically play minimal minions and use your hero power until they have Dawngrasp or are close to - It's so easy to disrupt their whole plan with Illucia or Mutanus.

Against Rogue, be very very careful about playing Voidtouched Attendant - I'd say maybe don't play it at all unless you have lethal. 

Handbuff Paladin can be a tricky matchup - this is where contesting the board is the name of the game. There have been times I've wanted to throw in Xyrella just for this matchup, but that's why Soul Mirror is here instead. 

Quest Druid is a nightmare. If you can use Illucia to steal Guff, you'll stand a chance, but otherwise that's a very hard matchup to win. 

Other matchups aren't that bad, I've found. You can push enough damage to ruin Warlock's day, and pressure DH a lot (which is hilarious). I actually haven't seen many Warriors while playing this, so I'm not so sure how that would go.
