Let's agree on this for the current tournament: if, in a battle, your Minotaur manages to block a maximum of two consecutive attacks between two saves, then the battle is considered valid. However, if three or more attacks are inflicted on him between two saves, the battle is considered invalid, even though it is theoretically possible to win it. Because it's unrealistic to conduct an entire battle where the Minotaur consistently blocks three or more times in a row between each save!
We will later include this in the rules or discuss a more acceptable option, although this one is pretty good.
