Try a sleeping or awake rainbow warlock pretender. He can actually clear indies/small armies once you give him some buffs. =) Spam send horror to cut off retreat path and evo your way through. Also in CBm, they're a great pick for Turmoil luck since most of your good mages are cap only and you also have a plethora of fire gems to alch when need be.
I honestly can't imagine what you need an awake pretender for, Abysian infantry make short work of indies, so that's 4 scales for something you don't particularly need. A Dormant rainbow isn't the worst idea for them, but you're going to need that extra 150 points to make it all worthwhile.
