You are overthinking it. You don't design fantasy cards with art to make sure all the technical details are right. You design them for fun and to make sure that the intuitive ideas and recall of all the python std functionalities remain at the tip of the tongue.

They cost 50$. The least they should do is teach me a certain amount of Python. Calling a tuple a "creature and a ghost" doesn't tell me what a tuple is.

You still don't get it. It's about drilling recall in a fun way, like Anki flashcards. You obviously have to use another source.

[dunefox]

Why not "drill recall" by actually using the language, for example doing advent of code puzzles? This is a lot of money just to have simple functions printed on playing cards.

Then don't buy it.

You may be under thinking it. You still want to capture the essence of the function / keyword in order to build the intuitive understanding and make linkages that help the reader remember.

Ex: One good thing about the tuple example is that it sort of highlights that we can have mixed types. The bad thing is that it doesn't do much else..

Well the first use case on the website is for someone who is 'looking to become a programmer', so it doesn't sound like the goal is simply for someone to recall their own knowledge of the standard python language.
