I use Ally: Any - Phoenix Down instead of Raise. Phoenix Downs have no casting times, are cheap, and don't use MP. Most of my mages' Gambits are for using status restorative items like Smelling Salts, Alarm Clock, etc. Ally: Status = Slow - Haste, Self: MP < 50% - Syphon, Self - Protect. I don't use any buff Gambits, I just remember to cast everything in battle so I don't have to mess with my Gambit setup.
