If you are using Lamasu, you won't have a spot for Emic anyway.
Coppercoin is not critical. He can be replaced by any buff extender.
If you have Hatter, he brings the Hex, Weaken, TM Boost & Buff Extension. He also has good base stats so he is a good option for the shield set.
This is my Titus Build. He needs more Def & more CD, but this is the best I can do right now on the Def with Merciless gear and I can't give him more CD until I can boost Wixwell's CD to stay higher than Titus.
