I suppose it depends on the context.
You could stick it to the outside bottom and then pull it out "apparently" from the inside
You could buckle the case while closed, get a little finger break at the bottom of the deck and slip it in
You could use a dupe
You could open the case to show empty and then leaving the case open slide a palmed card in
I think James Brown has a new effect out that deals with deck swapping and sliding cards into boxes in plain sight
Or, you could buy two boxes, build a really clever little flap on the outside, stick the boxes back together with magnets and invisible string but leaving the corner free for a peek.
