But what's the interest, and where will the intrigue be in the gameplay? The element of surprise will fade. Or is it just for laughs?

The interest lies in finding a setup where you play at the same pace as your opponent. A significant lag almost certainly means defeat here, but it also saves time compared to "I'm holding on until turn 131, and then my opponent kills me with two damage dealers after taking my main."

The described idea is not nonsense at all; at the beginning of my Heroes journey, I only played like this with friends – in hotseat mode, without looking away from the screen during the opponent's turn. We had quite meaningful games. And they were shorter – if someone gained an unrecoverable advantage, there was no need to waste time finishing them off.

Exactly, something like that. Also, when you see the opponent's situation, you think: should you take the risk and go for the 3rd-level creature on turn 121, or should you wait?

What's the point of this topic? )))

Well, everyone has their own point. Some people don't see the point in playing EBUS, while others can't be dragged away from it.

Also, because of questions like these, the rules are not entirely clear – how and how much to play, etc. It seems that the games should be shorter, but will they be short enough to, for example, play a Best of 3? Is a group stage needed, or should it be a single-elimination tournament (depending on the number of participants)?
