Well, they have some interesting cards.
Candit lets you draw two Cards if you Play her, though she has a high Morale cost so you Need a way to sacrifice her if you don't want her to become morale fodder. Same with her Thral, though I am not sure about that one. Dark Wish lets you draw Cards. If you build things with Sacrifice effects in mind, you may also want to consider Tormented Thral and maybe also Battlefield Scavenger. On the Genesis side there is Aleta Searcher for draw on demand Cards and possibly Aleta's Discovery if you Need a specific artefact.
For removal from game effects that you can use, go to Overcharged Bot, Overcharged Storm and Overcharged Bolt.
