I think if I replay from the point of capturing the yellow castle, my result will be slightly worse than yours :)
The thing is, in these tournaments, you need to change your tactics. And I had the stereotypes of a regular game against the AI: take everything with a strong hero. So after capturing the yellow castle, I just started guarding that castle instead of sending some sorcerer to capture the blue one.
Prorock, did a red player with genies come to you? Or was it just me who was so lucky?
And in general, has anyone fought genies? (It was a big problem for me!)
