What to focus on for a Trading Card Game? Includes layout sample

I’m new to Unity and my only programming experience is some HTML and Javascript awhile back. My goal is to take an already created (and now defunct) card game and turn it into a playable digital version. This is a personal use project and I do not own the rights to this game so I’ll be keeping my descriptions generic. I used FreeMind to layout what I need to do as far as implementing the rules and card designs.

I’m really only looking for guidance on where to start. I’m trying to stick to C# and I’ve done a lot of searching but haven’t found a straight tutorial for card games in unity. I’ve seen one that was for C# in a compiler program but I wasn’t sure that it would translate well. I’ve seen bits and pieces from other peoples’ questions that relate to randomly generating the cards and drawing hands but I’m not understanding what scripts get attached to what objects and why. I know some people are using external files to store data related to each individual card and call it as needed but I’m not sure how that works either.

I know this is a very involved undertaking and I’m not looking to have a fully functional game in a week. Any recommendations would be appreciated.

Card games would defiantly not be very good for a beginner at coding. You need to start learning the basics before you can start creating a much bigger game like this. Since you will need to create a card class and be able to keep track of all the different variables as things change, even the most simple of card games can be hard to code. So I would suggest creating something easier first.
