This event was given away to commemorate Pokemon Bank's first support for Pokemon Virtual Console games and Pokemon Sun & Moon. This Z-crystal is not obtainable prior to this event. As Z-crystals cannot be traded, there is no other way to obtain Mewnium Z (besides hacking). While this event can be received by any Pokemon Sun and Moon game of any region or game save language, the wonder card only comes in English.   Pokémon Bank Mewnium Z         x 1 0x3
