I'm thinking Rottkins for the most accurate shot with potentially Charlie next depending on what happens once Fading from Existence #5 happens which will reach 100% on the counter. Xlaw would be the 3rd choice imo due to pretty much 0 info around him. Destroya's slot was balanced on whether or not Charles was Krul and Rej's slot seems more connected to Witches than anything.
Maybe not the best thought process but I have a gut feeling Day 4 will answer a lot of questions from this
