True about the Basilica... but it also can persuade the opponent to keep the selected Creature away from you for a while. I have seen it result in a Creature one zone further away that otherwise would be helpful... very small impact, but sometimes helpful. And, of course, if it moves early and/or too close, it can get the extra die or two from attacks and has that slightly better chance for Daze or whatever. (I have use it in a Priestess where there were two LoD's and a Messenger, along with Artemis, and was impressed with the results.)
I think it is coming out, along with the two LoD's, Cassiel, and several spells that I had envisioned Cassiel casting. I think I'm adding a Mana Crystal and one or two larger Creatures... will have to see what that leaves me with sbp-wise.
Thanks for the comments. I really don't know what a good Priest book looks like, so this really helps.
