Thalia terrifies me. Secrets of the Dead looks very fun. Thought Scour is another card that threshold/dredge/whatever could use, but probably don't even need. Gravecrawler looks easy to break. Zombie Apocalypse is silly, but fortunately too expensive to be practical. Pyreheart Wolf has potential. Ghoultree is obviously overpowered, but there are so many other cards that do what it does that I'm not even sure anymore.
