I am browsing through legends, and, guys, I just found elf sun tzu. Kifino Tuftbalances. She has been in charge if her civs military for 200 years, and has not lost a battle she was in command of. She has fought 259 battles, all against a human civ, for 200 years straight. She is winning the war. By a lot. She is literally a great military tactician who would put Hannibal to shame, and is responsible for 4 major deaths by her own hands, a few minors that legends viewer won't tell me and I will have to find in in game legends, and 7000 military deaths from the enemy caused by her tactical genius against them.
