Wizards of the Coast, or "WOTC" for short, is the producer of hobby gaming systems owned by Hasbro, including Magic: the Gathering, Dungeons and Dragons, and the Star Wars TCG. From 1998 until 2003, Wizards of the Coast was responsible for translating and distributing Pokémon trading cards created by MEDIAFACTORY (then by The Pokémon Company). In 2003, Wizards of the Coast's license to translate and distribute Pokémon TCG card was transferred to Nintendo by Nintendo. After the license was transferred to Nintendo, Wizards of the Coast attempted to sue Nintendo, claiming Nintendo stole certain insider secrets. Both parties would later settle outside of court.
Expansion sets released by Wizards of the Coast
A set to follow Skyridge, titled "Jamboree," was in the works of being released by WOTC, but never had the opportunity to be printed, due to the cancellation of Wizards' license. Other consequences of the cancellation of the WOTC license was that there was only one print run of Skyridge, causing the price of the set to skyrocket.
Pokémon TCG books released by Wizards of the Coast
Wizards of the Coast released a handful of strategy guides to the TCG during the time they had the distribution rights.
