64 mystics has an upkeep of 768 gold. And then you have to add on some astrologers, some priestesses, and an army. I guess you can purposely kill them off to keep down upkeep but you're still going to need a large empire before you can count on getting a 3A mage. A Mystic with 3 in anything is too rare to be counted on as part of any strategy. You'll get some kind of 3-magic Mystic before too long, but it's not something you can plan for.
