I'm not entirely sure what you should take out but you should consider putting in:
Wash Basin (work on the bottom as well as the top, also works well with VP [which should probably go in somewhere too] and then Given Over to Egypt, put their SoG or other good card under deck, put it on top with Wash Basin and then d/c it with Given Over to Egypt)
Gifts of the Magi (if you're gonna make them draw cards you might as well draw some yourself and while you're at it Hospitality of Martha wouldn't be a bad choice)
Rain Becomes Dust (because you don't want them drawing the cards before you can discard them)
Lies (you're kinda short on battle winners and I don't think it's safe just to rely on your sites, this is a battle winner and if combo'd with Gen. Widow and RBD it can be pretty sweet)
You could probably take out Lies but other than that I don't know for sure. Is Satan's Seat just for Simon the Zealot and the likes?
