Wow that was fast >.>, well since you said add suggestions, I guess you can rig the defend command to give a set or random amount of mana as well. Heh, I got the idea to use accessories as a Guardian Force like item for some reason and thought that each GF would give a certain amount of mana per turn. Also another suggestion is pulling mana out of the monster with a FF8/ Draw like command, depending on their elemental settings. D, E, and F, give nil while C, B, and A give some amount.
