When designing a rogue deckbuilder / card game, how do you know if a card is final?
I didn't know how to word 'final' better, but I mean: I have gone over my cards a few times and I always change things. The first time I just went for interesting abilities, but I forgot synergies, so the second round introduced synergies. But now I'm thinking that yeah it feels good in theory, but maybe I forgot other aspects, just like I forgot synergies. But those are unknown unknowns to me, I don't know if there are other aspects I should think about...e.g. I don't want overpowered cards, so I tried to fix that too, and same for underpowered cards. But it feels like I could do infinite iterations, like, there is nobody that says "ding ding ding, the problem is solved, this card is FINAL AND COMPLETE!"
