To limit the values possible for a card's actual value, I defined `Value`

Is this the idiomatic approach? Is there something like Java's enum or
Pascal's subranges that I could use[1]?

Sicne I didn't notice anyone else answering this, yes the reason and way you wrote Value looks normal. There are preprocessors that can automate repetitive mappings, but I don't think they are an option to consider lightly.

The rest of the code looked normal too, but I'm not familiar with the domain to help more.
