Einzbern family wasn't good at fighting, as it is seen in 3rd Holy Grail War... They tried to fight but they weren't capable to win Holy Grail War. So they called well known magician, Emiya Kiritsugu, to join war for them (we are talking about 4th Holy Grail War). They summoned Servant Saber, Arturia Pendragon, and Illya's mother gave her command spells to Kiritsugu.
Explanation: That's why Saber said she was already in this time.
Explanation: Saber was alive Heroic Spirit (note: all of them have died and became heroic spirits and they don't remember if they were competing in some of 4 Holy Grails)...
