New update means new campaign!! This is the first campaign for Reconstruction of Byzantium. This one may seem impossible as the objective has over 60k health, but you don’t need to destroy him! Keep destroying the cities he goes to/prepares to go to and he will continue to flee until he reaches the top right. Keep your forces alive and drop some siege engines and you should do alright 👍

PS. If you take the cities before completely destroying the enemy units, they will turn into your allies!

Best of luck everyone!
