All of the battles listed, except for Anven-Deidra with version 3.1, have lost their relevance. The tactics and balance in these matchups have changed.
Out of curiosity, I watched all the battles, and to be honest, the gameplay amused me. There were gross mistakes made in all the battles, and on both sides. I was particularly amused by Ossir's game against Carli and Vitya's game against Garuna – they were clearly noobs. In this matchup, the ballista is usually killed on the first turn, but with such noobs (Vitya cast "Punishment" on the archers and didn't immediately attack with two paladins on the first turn), it's possible to win like that too... Jalib simply dominated against Iris – apparently, he didn't know that Rakshasas have the "Charge" ability. Carli – Nimues is a completely talentless setup; they could have skipped playing Nimues altogether, as he is clearly stronger. Letos – Nimues: personally, I would use "Dominate" – it makes the victory easier. Anven was clearly lucky with her "Enemies," and otherwise, she would have easily lost with that tactic. In the Carli-Helmar matchup, the "Magic Ward" rune is usually used, and without it, the defeat usually happens as in the video (although it depends on many things). Iris-Helmar: Helmar could have played better too. Why did he attack the archers (who deal negligible damage in this battle) at the beginning? It's a mystery to me. And in general, he should have retreated with his ranged units, used magic wisely, and won.
