Play as Inferno.

Wow, you're quite the hero player, aren't you? In my opinion, Deleb has no chance against machines, mass dispel, fire arrows, and skillful gate opening.

But I think Groll with machines (though sometimes OS doesn't have time to grab them, but it's necessary for the ballista), a developed gating skill, and deadly attacks looks more advantageous. Of course, there should be a cold spell in the guild, preferably a ring ;)
The main thing is to get rid of the dogs and build 3 mage guilds. Sometimes there's just not enough wood :( It would also be good to save the demons.
I once had some fun with a friend: He actually attacked my castle... now, knowing my tactics, he knows the countermeasure :)
However, I'm not sure I could calmly stand against him in an open battle :) but killing his 7 levels of development is a joy :)
