Well, I've finished the game twice and the only thing I'm missing is two lucky strip cards. There supposed to be 41 available and I only found 39. I think the missing cards are the dark knights (blue and green) since I see them in other people's packs but I never got them as reward. I got the purple knight card from Hubert as a gift after one of my furniture purchases. I think my issue could be related to the drunken Ghart card, which I got as a reward for the 100 LvL fight in the tavern after the bug fix which does not seem right. Seems like there should be a better reward for that game. I seem to recall finding it somewhere (not battle) on my first playthrough, but I don't recall where.

Any suggestions?

i was sure i beat everyone  but im missing a handful of cards, ughhhhh

i am missing a lot and i mean a lot

I've finished version 6.2 and now I'm only missing one card besides the king's (which is obviously not in this version). Did anyone get this card or is it also in the next version? I think it should be in the current version since the next updates are either outside the village or affinity dialogues.. 

Chances are the 2 missing cards are from the Kickstarter bonus content. We'll have to wait until it's available as DLC.

I got the bandit by challenging the underwear thief at night by the sword shop. He is level 28.
