All that remains is to add that with the same speed, the one who went last in the first round will go second in the second round (I might be wrong, but it's something like that).
So, the turn order still changes with each round. Therefore, if we apply this to my last example, the second round would be: Death Knights - Champions - Vampires - Griffons. If there were a couple more stacks of Griffons, they would go after the rest. It seems that's how it works. Thank you for your attention.
