Curse Demonlock

Hey Everyone!  Here's a Curse Demonlock I've been playing.  It doesn't run any new cards, which wasn't planned.  I wanted to try a curse deck w/ good Warlock cards instead of using the excavate package.  I think the deck is self-explanatory, but there are some good synergies that I didn't realize at first.  I may update with more details if it keeps performing well.  I'm not sure on the mulligan yet, but obviously keep cheap defensive spells vs aggro.  

I've been beating Rogues, Plague DKs and Druids, but aggro decks can be tough.  Though they don't seem very popular right now.  Maybe I've been lucky.  So far, I feel good going into any matchup except Control Warrior.  

Good Luck!
