That One Boss/Card Battle Game


 * The Vagabond in Yu-Gi-Oh! DUEL LINKS. This character's deck is an exact copy of a player's who scored high in the previous month's PVP ranked duels, so he's not only hard to beat, he's almost impossible to prepare for. He may even have cards on the Forbidden List, if it changed over the previous month. Of course, he gives out more XP and rewards if defeated than other opponents.
