Did a speed run of the challenge since I don't know if I have time to retry it; my schedule will be pretty busy in the next weeks. Prolly could have played better and lost less battles (although hax is always ready to ruin everything...) but still was fun and interesting. I used the same team that got me into 1880s for the Outsiders Challenge, since I really enjoyed building and playing it (thinking about an RMT on the topic). Edited the original post with proof. And, first to the finish line!
