Forum:Billy Deck

A Billy Deck is a Yu-Gi-Oh! Deck designed not for the purpose of winning, but for the purpose of enjoyment by the player utilizing it. These Decks are met with polar reactions by Duelists. Some find them useless due to their inability to compete with competitive Decks, while others find them a fun relief from the problem of common decks, as well as a relief from seeing Splashable cards. Billy Deck is named after player Billy Ye who is the first player to use this kind of deck in official tournament.

Most Billy Decks are modeled after Decks seen in the Yu-Gi-Oh! Anime/Manga. Other Decks have "fun" themes based on the duelist's personal interest. Below are a list of a few themes seen in Billy Decks and some cards that (can) accompany them.
