I've been wondering, where does this information come from about the new rulings/watermarked cards and such? I always seem to hear the info second hand and I'd like to stay on top of things.
Back to the topic though. Personally I think cursed blood gives more than it takes at this point. There are a lot of ways to counter/destroy cards in the staging area now but few that target things in the card pool. Plus death can really use the speed boost.
