Looking at the current spellbooks decks I saw....they are super boring, and they aren't even competitive anyway. This is a fun build I like to use, it focuses on making empress, but priestess is still kind of a win condition in her self, and world is there as kind of a reset option. If you really wanted to, you can just side in the cards that make this how it currently plays, with jowgen and stuff, but honestly that version just seems to lack the whole reason prophecy is interesting. adjust extra and side deck as you see fit.
