Card games basics plus a crazy eight example for renpy

The base classes you would need to create a card game plus an example game (crazy eights) made using only those classes and screens.
The advantage of using screens instead of labels for a minigame in renpy is: it can be called and played at any time in the game. also animating should be easier in screens but it might be just my preference.
