How to counter mind control spells (subjugation, blinding, etc.) used by a Necromancer?

Actually, the question has already been asked in the title of the thread. I've played against a Necromancer (human player) on medium and large maps many times. If he doesn't get the "Subjugation" skill, victory is practically guaranteed. But if the Necromancer acquires "Subjugation" (which is very likely on large maps, especially if there's a Dragon Lair), it becomes impossible to defeat him. In the last battles, it went like this... I had 200 Paladins and other units for Axel, and he only had 80 Banshees and other units (I converted a lot of Monks to his side). As a result, thanks to "Subjugation," spellcasting (he often moved around with his hero), high-level magic, knowledge, and education, he kept subjugating my units and using them to wipe out my entire army while simultaneously resurrecting himself. What should I do?! :smile21:
