Everything works as he described. In the first turn, the swordsmen get the advantage. The upper-left stack hits the horses. The right stacks eliminate the units with 1 health. Then, follow the instructions. Why a screenshot when you can try playing it out as described?
Overall, it's great, but for some reason, my horses die very quickly - first, they take damage from the upper-left stack, then in the 2nd round, the group stack hits the horses, dealing damage and blocking the marksmen, and immediately after that, the upper-left stack attacks again - this is where my morale drops, and the horses die... after that, it's just a matter of technique, of course, for the Griffins.
Who does the group stack attack in the 2nd round in a contested match?
