This card is one of two Pokémon cards that isn't actually a Pokémon, the other being Buried Fossil.
Even though this card has a clause that treats it as a Mega Evolution Pokémon, it is unplayable as there is currently no prerequisite Sachiko-EX card.
Sachiko Kobayashi is a Japanese singer and former member of the band Suzukisan. Mega Sachiko is a persona first adopted for her performance at the 2009 Kōhaku Uta Gassen. While in this guise, her appearance, along with the large statue that forms part of her act, earned her the nickname "The Final Boss" among fans.
