@CN, tech cannons, start whipping them every other turn. After that, whip some more rifles every other turn and once your stack is ready, kill off Toku. Once Toku is done, start killing off Catherine. Your economy will go in the dumps, but it will recover as soon as you get all those cities and make peace. Also, get that 2000ish gold off of Mansa Musa for Lib and Astro before declaring. You should easily roll over Catherine with cannons and rifles really. After that, it becomes straight forward. I couldn't be arsed to finish it off though.
But I have 24 cities, Toku is left with 2 that are far away and I have taken Catherines capital and 7 of her cities in total.
