SparkySweets, the idea was that the units on the map are strong enough, and to avoid significant losses, it's better to use at least either potions or magic. Plus, there are some optional but useful things like "Beacon" and "Eye of the Mage." If you don't use anything at all, you're clearly a more advanced player than I am, and you should have chosen a higher difficulty level.
RedHeavenHero, by the way, does it not show the yellow player's turn for you? Since the hero wasn't set up, it means the player was active.
