How do you think this team would fare against Heracles, summoned under Illya with God Hand active but Nine Lives suppressed?
Mash’s stout defense would be able to stand up to his assault for a time, more so if she were to employ Lord Camelot. But more crucially, between Helena’s Mana and Sanat Kumara, potentially Brynhildr Romantia, Qliphoth Rhizome, Troia Velos, and MHX Alter’s Strength, Mana and Cross-Calibur, they have amongst themselves attacks and weapons powerful enough to claim eight of his lives, more if the higher ranking attacks can claim multiple lives at once. Yes, it’s entirely possible (even likely) that Heracles would overwhelm them before they could capitalize on their strengths, but the chance of victory is definitely not zero.
