Always mulligan for EVIL Miscreant IF YOU GO SECOND. Otherwise, I usually dump it. You can keep Lifedrinker if you get a bad draw and you're going first and you don't want to risk an atrocious redraw. Edwin is not a new card--you should know how to use him--but just in case, if you get him at the start and have some other 0 cost cards, he's definitely worth keeping as a strong early play.
With this expansion, there isn’t a lot that I felt that improved my lackey deck except Pharaoh Cat . I also added 1 Shadow of Death . Further testing will reveal if I will add a second. SoD is a great play on Spirit of the Shark and Leeroy Jenkins. It’s a strong build already, and why mess with a good thing?
