Tactics in BATTLES

Hello everyone!
I remember one interesting game with a friend.
I played as Dungeon, and he played as Castle. We took over the entire XL map, and only then did we start fighting. I had two strong heroes. My main hero, Dass, had stats of 50, 42 (+/- 2), 28 (+/- 3), and 30 (+/- 3) thanks to various artifacts. When my friend saw my main hero, he just couldn't understand how I managed to raise the stats so high! My second hero was some kind of barbarian; he had high diplomacy and recruited a lot of neutral creatures: 35, 25 (+/- 3), 12 (+/- 4), 12 (=/- 4), and also had some artifacts, although not as powerful. Besides, he didn't have any artifacts that boosted morale. I only remember that my second hero had 100 unupgraded Hydras, 300+ Diamond Golems, 100+ Logs, 101 Archangels (my friend actually gave me money to upgrade them; I begged him). And some other creatures, but I don't remember who. Well, my friend played as a mage, and his hero had a mage specialization. It seems that his entire army consisted of Castle units: about 30+ Titans, 70+ Naga Sirens, 70+ Mages, 100+ Golems, and around 200 Gargoyles and Gremlins. His stats were around 25, 25, 20, 20, plus or minus 1. I set up a "zombie land" for him. My units just kept marching and eventually crushed him. I remember that he only resurrected with an Archangel once, and then it was over. His units were constantly being afflicted with curses. Even though my friend wiped out half of my army, I still upset him a lot. Before the battle, my friend said that he would destroy me with an explosion, and I said that I had a surprise for him. He only found out what the surprise was during the battle (a Sphere of Suppression).
