16th offline tournament “The Great Miner” on the map “Knotwork”.

I apologize if my idea is completely wrong, but wouldn't it be reasonable to introduce a second criterion that isn't the hero's stats, but rather the number of captured mines? In any case, tournaments focused on gathering an army and resources usually follow this scheme, for example, the recent tournament on collecting skeletons in Heroes II.

3. The goal of the game is to capture 10 mines of any type in the minimum number of days. All 10 mines must already be captured in the save file you submit!
