In order to avoid misunderstandings, this will be in english.
- If I didn't misunderstand papaours (please correct me), he said the point of having cards being upside down is so the opponent can read them better. That is totally fine, but you had some cards upside down, some regular, some tapped left, some tapped right and some lands in a pile and some on their own. It makes it more confusing when you look at the table, which is not a big deal in general but in a video where you want to showcase a format or explain the game it doesn't contribute to a good presentation.
- Having your lands above your creatures while your opponent has it the other way around is similar- it makes the battlefield more confusing than it has to be. Since modern magic has lands on the bottom and creatures on top, I feel that's the way all players should handle it for the purpose of the best overview.
- It is totally fine if the guy always plays Jund, it was certainly the right decision then. I just said that I myself would have chosen another deck. But I didn't do it and he made a good job! :)
Please don't take anything personal, just as constructive critisim! My original comment was a bit too harsh. All good :)
