Well, a quick rush isn't a good option either; you need to develop your hero to the maximum. Of course, he has a lot of troops, but with the right tactics, you should be able to defeat him. Judging by the logs, the archers only killed 64 ghouls, and you still have 800 of them. Defend, wait for them to attack you, eliminate the archers, heal, and resurrect your troops.
In the worst case, if you really can't manage, you can annoy him; you have plenty of time, and you also have more money.
Attack, kill as many of his troops as possible, and if you lose, you can buy back your hero and troops at the altar and attack again.
You have 3 castles, he has one; you have the opportunity to recover your troops, he doesn't.
