One more, you can do Light-Thunder team when Phoenix eido is re-released. Sol,Michael,Ramiel,Baal/Hermod/Uranus. Mike and Ramiel is a burst gauge filler (35 total from start is cool) and Baal/Uranus is trash-mob cleaner and multi-hitter. You can use that team to farm water advent event for water eidolon. Belobog is good too for extra atk-down, maybe for Ragnarok advent? that I don't know
