Ok, this idea came to me in some screwed up way...
When you fight Golbez, you "start" losing control of your own characters because of Hold Gas. I hadn't really thought it through before, but if you want the Hold Gas to not be effective.. you want to cast Mute/Silence on yourself. Since Mute status has a priority over Hold, it has no power over you. How's this useful? Well, it allows Cecil get ready his ATB bar while he does his scripted speech stuff... allowing you to revive other party members or get an early shot at Golbez.

Note: The reviving aspect should be done after the character dies at the hands of the Shadow Dragon.
Also, the attack should
only be made after "Mist Dragon" is summoned.
