Best way to introduce a game map class in C #

Question

I use a Class Card, which contains 2 enumerated properties (the set is diamonds with diamonds) and the value of the card is from 2 to A. And overrides the ToString () method to return something like Ah Ad, etc. Everything is fine, but the enumeration value can't start with the number, so the value of my card listed looks like x2, x3, x4 ... it's not pretty.

You also need a simple approach to analyze multiple cards from one line.

Who knows the best design approach for this class?
