Cross-Region Siege Day 3

Image 1 shows the score at the end of Day 1. Image 2 shows the score at the end of Day 2. If the randomly assigned three nations form an alliance, two nations can team up to control the score and tie for first place, which can yield better rewards. If all three nations are allied, it seems like you can exploit a loophole to tie for first place. Image 3 is the map at the start, with all three nations having equal castle scores for a fair beginning.
