Solve this puzzle/riddle, save a puppy
A friend posted this on another forum so I thought I'd share it here..
Yes, it is I, the sometimes-super-villain, sometimes-superhero. Today, I have captured a puppy, as pictured:

My device of torture? A suitcase... of DOOM!


The suitcase has a four digit code, which can only be discovered by solving my riddle:



Since I'm a nice guy...and maybe a bit schizophrenic, I'll help you out a bit. You must replace cards from the top with cards from the bottom. After you have done this, the cards at the top will tell you the code.
Best of luck.... And you'd better hurry. Grandma's suitcase is air-tight!
(No one solved it in time so I'll give some additional clues: The bottom cards are not arranged in any particular order. They're just a pool to replace from. For combination possibilities 10 = 0 on the suitcase. Suits do matter but not as much as you think. I'll give the answer in 2 days)
