How to play against Wizards?

The thing is, I actually tried to rush. The only thing is, I spent one day gathering experience and troops, wandering around the castle. On the 5th day (the first battle took place), I had about 170 skeletons and a small group of zombies. One opponent had 14 gargoyles (2 types of 7 each) - Nazir; the second (Orax): 40 gremlins, 14 gargoyles, 9 golems. In the first battle, I lost almost 70 skeletons before he retreated. In the second, I retreated; Orax was dealing about 200+ damage with his ice spear and wizard's staff. At that level, I had nothing to counter Chaos with. At the time of the battle, I had upgraded: Advanced Necromancy (spiritual bond) and Advanced Mechanics with a Plague Tent. In general, I tried to rush as best as I could. But, unfortunately, I didn't have enough experience. And right after the battle with me, he took the Utopia.

I just haven't encountered such an aggressive opponent before. That's why I asked for help from experienced players. After all, a quick start is 70-80% of the key to victory. And when they take the Utopia right under your nose (and that's a huge bonus to money, artifacts, and top-tier spells in the first week), plus you retreat with a significantly depleted army - that's not good.
