Really polished and it surely has a specific creative direction, which is amazing for a game jam project with a team of this size (it's not easy to coordinate so many people)
Premise: I love card games so I'm the target and I know poker rules either (I'm currently developing a game called Poker Monsters maybe you could like it, it's here on Itch)
I have to say that I don't enjoy this game as much as I was supposed because I find the twist not so intriguing, you basically add another win/lose condition to poker without designing enough around it and the feeling was to play two different games forced to stay together.
I think it would be a lot more interesting seeing other players attack/defense cards because allow you to strategize on the classic Poker part of the game.
Except for the game design it feels like a complete game thanks to its polishing level so well done!
