What kind of magic do you like?

I wouldn't say so. On the first turn, Lifegiver casts Angel on himself. The Death Knight casts Anti-Magic. The Mage just stands there. Then the Death Knight summons. Here, the Mage casts Hypnotize. Even if he is killed, Lifegiver will resurrect him with Hand of Fate. Devils or whoever else there, will one-shot the Death Knight. And that's the end of the story... Besides, when I tried this battle, the one who attacked went first, i.e., I attacked with 2 heroes. And the Mage went first. Here, Hypnotize is also useful.
Even if you hide the summoned creatures behind the Death Knight, it won't help: Hypnotize works regardless of visibility. Just so you know: Blindness was not applied. Hypnotize worked perfectly.
The Death Knight cannot win with Hand of Fate: if he kills the Mage, Lifegiver will resurrect him. Hypnotize. If Lifegiver is there - Hypnotize anyway...
So, two heroes with one spell turn out to be better than one with two spells...
