///
/// - `color()` - returns the color of the card based on what's configured at the type parameter's implementation of the `DeckedBase` trait.
/// - `fluent_name()` - returns the long name of the card from the `Named` trait's use of fluent templates.
/// - `from_str()` - allows you to create a `Card` for the specific deck with a string representation of the card.
