Dear Alan, I would like to know if a walkthrough will be accepted (and under what conditions) in which several minotaurs wipe out armies that do not deal magic damage, which is possible due to their ability to block attacks and a high number of re-saves.

For this tournament, let's agree that if your minotaur manages to deflect a MAXIMUM of two consecutive hits between two saves in a battle—then the battle is realistic. However, if three or more hits are dealt to it between two saves in a battle, then the battle is unrealistic, although theoretically one could win that too :) Because for an entire battle, every time from save to save, the minotaur's block always triggering three or more times IN A ROW!! Well, it's just not realistic :)
Later we will add this to the rules or discuss a more acceptable option, although this one is great too :)
