Excellent answer!

While I do not understand a lot of the code, and mostly what things are assigned to which class, I will study the code and try to incorporate it into my game (I don't like code I don't understand, hence my dislike towards snippets)

I decided the following things, although I do not know yet how will they affect the code.
-There is only bad card (9 of them in a deck) and the X card.
-Also, an X card is ALWAYS present in each turn. So, each turn contains 2 bad and one X.

My main question before I start reading the code, apart from the Core class, all the others are linked with what?

I'm sorry, it's just that it's an 101 course for Flash and we have done nothing more than AS linkage on the library (no class coding, although I know about classes from python, but it seems way more complex with AS)
