Tactics for the Stronghold.

So, generally, in most cases, I usually prioritize increasing growth and income first, but if I'm going to play against a Castle or Academy, and the map has all the necessary resources, especially crystals, I try to build creatures within a week, as they are the main offensive force. It works even better if the second unit is already built, because for Behemoths, you need the Wolf and Bird dwellings – that's 3 days in total. I build Cyclops last because they are expensive; they are mainly for destroying walls. The Mage Guild up to level 2: Lightning, Haste, Slow, Blind, Cure, and then forward. Of course, before that, I increase the hero's attack.
