I don’t know about Evocators but you are correct about sequitors. They really have just 4 maces. I guess reason is that they obviously chamged their warscrolls, but not boxes. Warscrolls which came with soul wars said “ome mace in every 3 sequitors + one for prime”. It’s 2 of five or 4 of 10. With this it makes sence, but actual warscrolls say “2 of 5 “
