def deal(player)
  # Add the next card in the deck to the player's hand
  # We need to copy the card object from the deck before appending to the hand
  # as it will be referenced otherwise. This can cause the deck card to be 'faceup = false'
  # when we set this attribute for the dealer's second card. This will mean that when the
  # deck loops around on itself, that card will be dealt facedown which is wrong!
