Like everybody else pointed - please stop switching the camera when the Red Coin Players makes a choice or is doing a mulligan - it's so confusing and brings nothing to the game. I would suggest this, cause seeing the choices and the actual choice that the player makes between cards is actually really important: make the top of the Screen where Red Guy is to be the window which we see when he is playing:
Other solution will be if you design something that will make both players to play from their respected side of the Board, like Red Player is looking at his hand and playing on the top of the Board, instead at the bottom like we are all used to. Meaning that Blue Player will always play at the bottom and Red always on the top of the Board.
The deck diversity... this is tricky. It will be nice for players to be able to change stuff, but a whole deck? Well, if this is a RULE that you must change a deck after day one what sort of a rule should it be? Should the player be forced to change the one deck that was Banned during his first game or a deck that he thinks under performed? Or maybe put a cap on cards that might be changed in a single deck - 3 Bronzes, 2 Silvers and 1 Gold. Or maybe players should chose just one of those. This matter needs serious debate and you should definitely communicate this with the said players. You can even run like tryouts to see how this actually works, cause it can lead to HUGE swings. Also, should it be MANDATORY or VOLUNTARILY. And this is a huuuuge question.
One thing is for sure though - this right there will bring a Wild Card element in the games and will make it way more intense Day 2.
The guest hosts... I get the idea behind this, but maybe give them some different role. Like, what are their strengths? Telling stories, conducting interviews? Maybe just let them explore the surrounding area and communicate with the actors, let them play a game of Gwent with an actor during the breaks (Swim and Jaggerous can do excellent here, as they are really familiar with a lot of meme decks), maybe even do a 1 hour pre-show with this, let them play with some meme decks and I am 1000% sure this will be way more fun for everybody involved. I think this will be WAY more attracting than what we have now - guys trying to pump you up for something they do not really understand. It's kinda uncomfortable from both sides of the screen, I believe. Like, Jesse seems like a really, really nice guy, but he was put in uncharted waters and this was what he was screaming in my face, while looking so sympathetic at the same time.
Someone else suggested invite some gaming journalists - maybe link them with the host and make them explore the things I mentioned above, maybe not, but I find it an excellent idea. Than criticism or high praise - you'll know from first person and will have a way better idea of what and where to actually improve.
The costumes... I have one remark - costumes are really good looking, but they do look way too tidy. Maybe they need some crumpling, especially on some specific characters and especially if those characters are in the muddy and dirty woods or whatever (miners, peasants). I am not saying ruin those costumes, but they do look way, way too tidy.
Also, Pavko (my regards) - can he please stay in his costume all the time or if he is not, let him not switch between Pavko and Pavel while the show is on? I mean, if he stays there like Pavko it will bring so much more atmosphere while the event is going.
I am not in a mood for criticizing stuff right now, though it may seemed so with some of the above observation. Main thing I have problems is right now is the state of the game, but you already know that. Those Create BSs that decided games, especially the Nekurat in Final... this was just atrocious.
Best regards,
Borislav.
