Well, I think I may roll with UmiYama teams then. Though I may run the high-risk one more because even with the more defensive team I'm pretty sure Hera can still one-shot me. I'm not afraid to spend a few stones though, considering a Hera is MANY times better than a round in the golem and knight machine. Question is, Hellray Harpie Demon or Susanoo, and Dark Liege, Vampire Duke or Love Deity Chaos Venus?
I'm reluctant to trade out HHD because if I pull off a good combo with Venus at his side (I'll pop Drops before I pop UmiYama so I have more light orbs, and then pop Venus for Change the World) I'll be doing a TON of damage to Hera. Susanoo is more defensive, however, and Vampire can give emergency dark orbs just like Drops can give emergency light orbs.
