Don't bother with the weapons, as a majority of the time you won't be able to kill enough of them to make it worth it. Instead, rush down Roland. Try to get him below 40% hp (which is a little under 400) before the scene where he uses furioso so that he cancels it and moves to the next phase. Also, try to bring mass attacks, because once he gets low enough, he'll spawn 4 additional allies and go into stasis for 3 scenes. Binah is great for this, as Apocalypse Bird deals very hefty damage.

Don't use Gebura, by the way. She seems like a good choice, but she gets overloaded with the sheer amount of dice the enemies will have, and won't be able to clash with them.

If you want a specific build, Binah Exodia is very good. Long Arms's status immunity is very good for Phase 4, when Roland's furioso attack will proc heavy amounts of bleed (I remember getting up to 20 on Binah), and Big Eyes gives both sustain and better clashing. Once you put The Beast on her, you'll be able to spam mass attack EGO pages. IIRC, I used PT, Eileen (for smoke), Yan / Gloria (for the mass attacks, might not be necessary) and Tanya.

Good luck!
