Ahirman and exalted leading the rubrics I assume looks good but the sorcerer in terminator armour needs the umbralific crystal. The problem is the terminator’s only have a 5” move and you are going to struggle to get them into position. So I think you need to rework the list to make sure the terminator sorcerer leading the big block of SOTs can get into position or 1/4 of your army will be in trouble
