Who do you think will win?

At first, I rushed and agreed with Forrest :) But then I thought about it and I accept your challenge. I'm ready to win 10 out of 10 games with Gunnar (though maybe 9 out of 10 if I rush).
But, this will only be the case if the troop arrangement is not changed. In this case, Vidomina won't make a single move in battle, and not only will Gunnar win, but he will win without the slightest losses. It's all about tactics, with everyone moving forward. The first move is a berserk attack on the angels, skeletons, and ghost dragons. The goal is to kill all of Vidomina's troops without letting her make a move at all. Black dragons kill the black knights, angels attack the liches, leaving 10 of them. Ghosts under berserk attack the vampires, they retaliate, and 16 vampires remain. Scorpikors kill the ghosts. Vidomina's angels under berserk attack the skeletons and die in retaliation. The eyes with harpies finish off the liches, and the minotaurs kill the vampires. That's it, Vidomina is left with only a stack of skeletons under berserk. Next, we summon fire elementals, use them to remove the retaliation from the skeletons, and attack with everyone. 3-4 rounds and the skeletons are dead again :)
Losses: only the summoned fire elementals. Gunnar has a large advantage in troops, so there's no need to even think about who to kill first.
