How to win with a “weak” Knight?

2 PReDS
Colleague, but still, a person is unlikely to spend precious gems and sulfur on a couple of guilds of mages, playing on Good and Evil for warlocks...

If someone could play as a warlock against themselves on this map, that's exactly what they would do. Warlocks on gargoyles with magic would control the approaches to Dragon City with the task of weakening the army of the power hero if he tries to attack. With troops from dwellings, of which there are many on the map, and not far from the warlock's castle, he would defend resources. And, I'm sorry, it's not so easy to dig out knight troops from the castle in the second week of the game, and it's impossible to defeat a skillful player.
If I played as a knight against a human player - a warlock, I would try to capture Dragon City, and if he actively opposed such attempts, I would try to take the sorceress.
