So to simplify "how do you go about hurting Saber": you don't cast spells at her, and treat her like any other high-powered magical knight. Think big or get really good at stabbing.

"Punch her really hard. If that fails, hit her with a really heavy, really sharp thing. If that fails, shoot her with a really big gun."

That's pretty much standard operating procedure for the people on the UMMA side, really. Most of them are supreme ultra-warriors who are the last hope of their worlds.
