convert a String to an Object of specific type

I am saving a series of Card-like objects in a database, to save them I had to implement serializable, the problem is that I do not know how to regain that object, I made a query that returns a cursor in whose position 3 is the serialized string of the object and I want to convert it again to letter but I do not know how this is what I try but it does not work

Cursor c3 =dm.selectDeck();
        c3.moveToNext();
        Card ca=(Card) c3.getString(3);

this is the string that is obtained from the cursor

  

Card {card_id = 1, name = 'aquarius', heal_Points = 1, attack_Points = 1, defense_Points = 1, magic_Points = 1, speed = 1, loading_Speed = 1, attack_One = 1, attack_One_Description = 'descAttack1', attack_Two = 1, attack_Two_Description = 'descAttack2', photo = 'aquarius', cost = 20}
