Just wanted to share this team. Figured I'd use the awesome English PDC-esque tool made by @Mapaler to do it. I've been using this setup and my own Tifa to farm AA2 easily and without having to worry about finding the right friend with the right equip. Yusuke should have VDP SA and Tifa has 2x Devil Killer and 2x SDR latents, just forgot to add them. Honestly, nothing is that scary in the dungeon except maybe Keela, and even she is stallable with huge shield uptime from Tifa + Yuna and hearts from Cotton.
