The draw was average, but there were two experience stones. At first I thought about leveling Marius, but Arlach gets earth magic, so I level him. The secondary hero is far away across wasteland, reaching it by the end of the week. At home, Efreetis in the Citadel. Then in my treasure zone, I take +4 attack, wait for the growth, and with it take a Dragon Fly Hive for 8 Wyverns. I run through a teleport to the opponent's treasure zone, kill the main hero at the start. Then a bit more and he surrenders.
Thanks for the game!
