Greeks/Heretics overlap with a few of the stronger characters so if I'm reading your requirements correctly, one of those defenses would be lacking some oomph because Philetus, Hymemaes, and Diotrephes can only be used for greeks or heretics, not both. You're going to have a similar thing with Giants/Philistines/Canaanites. (unless I'm reading incorrectly)For your purple, the only good Israelite kings were David and Solomon. All of the other good kings were of Judah after the kingdom divided after Solomon's death. So a lot of your identifiers will say King of Judah. If you had Saul, David, Jonathan, Solomon, Mephiboseth, Bathsheba, Abigail, that gives you 7 Heroes so maybe you include Jehu to get to 8. But I say all that to say that you could have another set for purple of Kings of Judah because there are 8 of them. (Amaziah, Uzziah, Joash, Josiah, Joram, Asa, Hezekiah, Jehshaphat)
