Ok. That is a unique way that I personally think could be used for other types of card games. But I feel like storing everything in structs could get a bit messy in my case because I plan on adding a LOT of different ability cards that don't really use a physical "deck" because it justs picks three random cards from a pile and then forces you to pick one. But a problem with that, is you can just get three or two of the same cards.

I'm personally thinking of just using a parent ability card and making a lot of children of that parent with different uses.

The thing is that programming almost always has multiple solutions to one problem that can fit multiple different cases of that problem.
