I normally use Sabin Locke and Edgar but let's just see if I can put Cyan in there. I normally have Cyan with Cure2 and the other people with cure. Keep Locke in the back row and keep him using cure every round on the whole party. I normally only take out one of the arms but I can't remember which one. Have Cyan use Quadra slice. Put Sabin in the back row. If you know how to do it have him use Suplex if not just use pummel. You will most likely destroy both of the arms with Cyan and Sabin anyway so that leaves the main body. If you have any level two spells just blast away with them.
