Post-match analysis.

1. It is beneficial to upgrade Centaurs at level 111 when there are many of them, or if you have three native heroes or hide them nearby. 2. Why upgrade Elves? In my opinion, they manage well on their own – test it yourself, for example, by trying to break through the maximum defense of a Necropolis with 7 Elves or that Horde of Mummies. 3. Instead of upgrading Centaurs, you can bring in Pegasi and Unicorns and place them on individual tiles with Pegasi. 4. It is definitely necessary to break through the Mummies – even if it results in significant losses – as it will open a direct path. Mobility is key. Besides, Mummies are the easiest guard to defeat, unlike, for example, Harpies. 5. And it is always desirable to buy as many heroes as possible – in this case, if you don't send the Warlock back to the castle to upgrade Elves, he could have revealed more of the map.
