So as a new player dude, it's worth pointing out that armies with old or no tome like Everchosen and StD are going to struggle with newer tomes.
There is almost certainly a new Everchosen book coming, or a StD as one of the big playtesters is building and using one, always a big giveaway.
I would get the AoS app and filter for those keywords, and just have a general read of the scrolls for a starter, there might be something really obvious you have missed. One of the faction chats on here would be able to help you as well if there's a StD one
