What skills do I need to make a card game?

Hi! I’m completely new to Unity (not to programming) and I have a grand project in mind: a card game with a really special economy. However, I don’t have any idea as to what Unity skills I might need to make even a basic card game in the first place.
There really aren’t that many tutorials on the topic but if I know what skills I need then I can search them up on Unity Learn and be miles ahead of where I am now.

The basic idea is a Pokemon-like game with procedurally generated cards that have different stats and can be stored and traded.

Have a look at this course, this explains how to make a basic battle card game, I learned a lot from it. I’m sure you will find your way into your own card game through it.
