At the start of turn 3 without mana, I took two Dragon Utopia with stats. Flight was obtained from the 3rd upgrade, DD from the 4th. Flew to reclaim cities. TP was not given after 3-4 upgrades. The opponent decided not to wait and surrendered. Throughout the game, their army appeared larger, but there were no stats, and nowhere own particular place to run.
Thanks for the game!
