Is there any better deep clone methods for list?

So I needed a method to deep clone. I wanted one list of cards to equal another list of cards, but then I also wanted to modify one of the clones.

I made a method to copy the list like this:

    public List<Card> Copy(List<Card> cards)
    {
        List<Card> clone = new List<Card>();
        foreach (var card in cards)
        {
            clone.Add(card);
        }
        return clone;
    }

and use it like this:

        _cards = new List<Card>();
        _thrownCards = new List<Card>();

        _cards = Copy(_thrownCards);
        _thrownCards.Clear();

I'm not experienced in C#, but somehow my gut feelings tells me my copy method could be made simpler. Isn't there any other way you could deep copy a list? I tried using MemberWiseClone, but that just created references to the same object, not cloning it(maybe I misinterpreted the MemberWiseClone method).

Do anyone have any tip how simply clone a list object?
