One way to do it is to set a property on each card every first time it is
viewed, and then check the property whenever you revisit the card, something
like:

  on preOpenCard
    if not the uInitDone of me then
       doMyInitRoutines
       set the uInitDone of me to true
    end if
    doOtherStuff
    ...
  end preOpenCard

You may have to account for other behavior depending on whether your stack
can be saved at any time during its use as properties (init values) will be
saved with the stack.
