Aesthetically it's a fantastic experience. Thank you.
I don't usually play card games so it was very strange that I build a deck and the whole interaction unfolds automatically afterwards. It's an interesting design decision. It may be better to somehow telegraph/mentally prepare the player. As a new experience the choices at the start can be overwhelming while the execution can be underwhelming - too much control then none. Does that make sense?
I managed to win by a lot (20 years) but honestly I have no idea if it was because of good choices or chance. I guess the game was not clear enough (to me).
It's an interesting idea and well executed. There's potential to expand it. Good luck
