Playing more of Insightful Aid. I put ONiON on Six, since he has an even stronger "DMG when hitting debuffed enemies" Insight effect than Bkornblume. I gave Leilani to Bkorn, since Leilani also has strong Aid Incantations. I also brought Ulu, because somebody had her set to Assist and I wanted to try her. She's kinda bad, but I did find Avgust's Aid Incantation to be really useful for this fight since it's a Mass Attack that can dispel.
I'm hesitant to call this Catalyst broken, just because Arcane Lantern also has some ridiculous shenanigans, and I had a ridiculously strong artefact layout. But it does seem like Insightful Aid has a really easy time with this specific fight (if only because you can easily kill Razor's minions for constant Stamina regen).
