... what kind of teams are people fielding?

Without Oberon, I'm finding it difficult to make a proper team. Despite having three SSRs:
Odin, entirely unusable due to taking double damage 3/8 turns in AAB.
Gaia, who would be amazing when Awakened, but without, she's largely useless in AAB.
Titania, who is entirely braindead in AAB and is literally only good for her +30 self-Burst generation every 4 turns.

Eventually I ended up with Mordred with Trial by Jury, Titania-Scathach-anyone-Sol. It's... such an awkward team with -50% Atk and -25% Def, but it works.
I've also tried Cass with Black Propaganda, Titania-Scathach-Cybele-Sol, but -35% Atk and -30% Def with no Blind and Charm tends to end in disaster even with double heals and double Dispels.
