fine geek toy, but seems overly complex.  I threw this 
together long ago, to simply replicate a shuffling and deal, 
selection without replacement of an arbitrary input deck of 
letters, numbers, symbols, whatever.  Add UC. Stack or bias 
the deck to taste.  Run lots of rounds

Print a screenful, and choose a line and offset with a D & D 
20 side die for your seed.  Print a sheaf of them, and toss 
the paper into the safe in a tamper evident safety envelope
