You can shuffle a deck
You can shuffle a deck of cards into oblivion in only 5 or 6 shuffles, but only if you are skilled with the riffle and split the deck into unequal portions. The average shuffler will require seven riffles, while the overhand shuffle is nearly ineffective in randomizing the order of a deck.
