Some duelists have extra requirements to unlock. You must constantly meet these requirements or they will vanish from the selection screen. If you defeat a duelist with special requirements ten times, they will be permanently selectable, regardless of their past requirements. For example, if you defeat Joey ten times, you can then duel him even if you have a Jinzo card in your deck. Note: Losses and ties do not count against your total wins.
