Bugs

 * Dropping one of the cards and picking it back up again will increment the card count, effectively removing the need to pick up at least one of the additional cards in the hand.
 * This exploit is only possible if the cards are somehow not automatically added to the player's Caravan deck when initially picked up.
 * The card count may not be increased when first picking up a card in the dead man's hand.

Behind the scenes
The "dead man's hand" is the poker hand purported to be held by Wild Bill Hickok immediately prior to his murder. Although the "aces and eights" combination is widely associated with the hand, the fifth card often differs depending on the account. The Queen of Clubs is claimed to be the fifth card by Ripley's Believe It Or Not.
