Cheat Engine

So my little brother loves Marvel Snap. He has been playing it almost non-stop and is pretty good at it. However, he has troubles with his eye sight and it's getting worse every year. He can not play it on mobile, and even PC is becoming very tricky now. Since I am a software engineer, I decided to go look for some solutions. One idea I had was to use Cheat Engine to create a read-only tool that would read from memory all that happens, and I could make it into a voice-over describing to him what the current situation is. It's a cool project for me to get into memory stuff and ethical hacking, and I'm helping my brother continue to play the game that he loves. Anyways, enough backstory.

I started with the tutorials in Cheat Engine and that brought me pretty far already, but I am hitting some roadblocks. I'm not sure if you are familiar with the game itself, but basically it is a card game where you have 3 locations, each location can have at most 4 cards, and there are 6 turns each game. The goal is to have the highest power in 2 of the 3 locations.

I thought I would start off easy by finding the address for the power stored for my side of the 3 locations, and that went pretty good. I tracked it down in a game, stored it, but then I saw that it changes each game, and it wouldn't work anymore. I thought it might be something like restarting the game, so I created a pointermap, tried again for the same location and got another address. I created another pointermap for that one, did a pointer scan for the two and found some possible base address with offsets that would lead me to the power of the first location, even in a new game or after quitting and reopening the game.

That all worked well, but now I'm trying to read the information in the locations itself, and I have no idea how to start on this. I'm not sure if I should focus on the data structure where I found the power, or if I should find some way to figure out what array is changed whenever I place a card. I'm also not sure if placing the card actually happens when I move the card, or when the server plays out the round. Any pointers regarding all this, how to continue?

Never played it, no idea what it is.

From briefly searching around, it seems to be made using unity. You can probably use CE's mono features to get a really good idea of how the game works.
Look at the top menu of the main CE window. There should be "mono" or something up there after you attach to the game. Activate mono features, dissect mono, and start looking around.
I'd use code injection after I find something suitable. You could use pointers if you can find a static base.
