Here is one way to shuffle using linq. The 5 random cards are the first 5 items in the list. :

    class Program
    {
        static void Main(string[] args)
        {
            List<string> deck = new List<string>() {
                "S2", "S3", "S4", "S5", "S6", "S7", "S8", "S9", "ST", "SJ", "SQ", "SK", "SA",
                "H2", "H3", "H4", "H5", "H6", "H7", "H8", "H9", "HT", "HJ", "HQ", "HK", "HA",
                "C2", "C3", "C4", "C5", "C6", "C7", "C8", "C9", "CT", "CJ", "CQ", "CK", "CA",
                "D2", "D3", "D4", "D5", "D6", "D7", "D8", "D9", "DT", "DJ", "DQ", "DK", "DA"
            };

            Random rand = new Random();

            deck = deck.Select(x => new { card = x, rand = rand.Next() }).OrderBy(x => x.rand).Select(x => x.card).ToList();
        }
    }
