You have not explained well what you are trying to do, but possibly
you want to loop through the cardlevels instead of the cards, then for
each cardlevel you can obtain the card aswell as the other data, so
something like

<% @user.cardlevels.each do |cl| %>
<%= cl.card.name %><br>
<%= cl.other_data %>
<% end %>

You might need to check for cl.card nil though.
