Counter-heroes in duel mode (3.1).

To put an end to your arguments, I recommend first killing the Titans and Mages, and then applying "Sorrow" to the Golems; let's see how lucky they get. Just Obsidians won't be enough.

Thanks, we've already come to the conclusion that Ravenna is stronger.

Yesterday, I played against an opponent who always uses Ossir. I, accordingly, used Iris. We played about 6-7 times. I only lost once, and that was by chance. My opponent has a higher rating than me. Therefore, I can conclude that Ossir is weaker than Iris. There's no point in posting replays; everywhere it's the same: everyone around is using armored units, Griffins attack from the sky, Iris places Secret Crystals, Monks bombard the Archers, and Archers die from the opponent's volleys.

A player on the "Yubileynaya" map who only uses Ossir is, by definition, a noob, and the rating here is not an indicator; we know how people inflate their ratings:smile42:.
When playing against an experienced player, it might happen that the Griffins attack from the sky once, and even then, they might miss. Ossir can split the Ents into 2 stacks, and the first dive of the Griffins might be their last. Their morale might save them, or it might not. For Iris against Ossir, the only tactic you described is the one that works. Ossir, on the other hand, has several. Of course, sometimes a well-placed line and luck can work in Iris's favor, but they can also work in Ossir's favor.
