There's a Dutch card game called Rikken that intentionally incorporates bad shuffling. It's a trick-taking game, so the cards get clumped by suit during the hand, and you shuffle very lightly between hands. After shuffling, the cards are dealt several at a time to each player, so players tend to get much more suited hands than with a well-shuffled deck.
