Probably an easier question to answer if we could see the models
involved (and perhaps an English description of what you are wanting to
achieve). My gut feeling is that this is either as simple as you get or
else it should be possible to fold the exclude directly into the "cards"
queryset without having to do an explicit extra query. Which alternative
is possible depends on your model relationships.
