Well, 21 Mark clearly didn't deal much damage here; morale was high at the beginning, and the main hero was present, so the battle was still challenging, and I managed to win it with some difficulty, much like I did at the CIS tournament in Odessa on map 117, where I defeated 99 Dendroids using Angels and Tyrus in the Void Tower with just wolves and single-unit attacks (h3dm1). There was a chasm across the entire battlefield, with 2 cells passable at the top and 2 at the bottom, which ultimately led to my defeat. Later, I managed to win, but I was too nervous at the time.
