Light team is doable.

Using Sol, Metatron, Belebog and Artemis with St Nich as your main eidolon. Use Gawain with Sniper Shot. You'll have -55% atk and -40% def but you will have no Black Propaganda, though the -55% attack might be enough to help deal with another overdrive or two depending on the run.

If you ever get Diana, change Gawain to Mordred, still with Sniper Shot.
