Loved it before, love it again
I enjoy the changes you made to this game. The creature changes were really good and the new art is not bad at all. That being said, I believe you should put a lot of weight into what the user Arcengal said. He is absolutely correct in all what he says. As a long time player of card games, I know that these facts are true. Also, as I have said earlier, Taint being always cumulative is not so good. It overpowers taint, so that whenever you're tainted, you keep cursing and praying for a remove taint spell. Now, if taint affected sanity, or if some cards were cumulative (such as Curse of Cthulhu) while others weren't (such as King in Terror or Blessing of Hastur), that would make it much more balanced. Also, one last note: Betrayed should have a sanity cost. In fact, it should probably have sanity cost 2, because that way, not only is it useful when your opponent has no creatures (discard to gain 2 sanity) it also compares fairly with the other damage spells that use arcane.
