Sonansu made its debut in Pokémon Tretta Fes Set 3 and those that traded in their SUPER CLASS (8-19) or NORMAL CLASS (8-39) Sonansu by putting the Tretta in a special machine could then exchange their Sonansu Tretta for an event download version of it for their Pokémon X and Y games. Tretta players though lost the ability to use that Sonansu in Tretta as the machine returned a blank version of the Sonansu Tretta.


The exchange machine was available at the Pokémon Card Game Battle Festa (ポケモンカードゲーム バトルフェスタ) which was held on December 15th and 23rd, 2013, at the World Hobby Fair '14 Winter (次世代ワールドホビーフェア'14Winter) on January 15th, 2014 in Nagoya, January 25th and 26th, 2014 at Makuhari Messe, on February 2nd, 2014 in Fukuoka and finally February 9th, 2014 in Osaka. The machine was also available at the Pokémon Centers from January 20th, 2104 through February 16th, 2014.
