Hi,
Well, the document copy still exists in 2013, the list item copy itself has been deprecated on the new workflow engine, what you can do though is still utilize the 2010 workflow on 2013, with this you will be able to still copy the list items.
Some discontinued features in SPD workflows on 2013
