A new “Mimikyu Pin Collection” will be released in America and Europe on April 7th. It will come with a foil Mimikyu promo card, a collector’s pin featuring Mimikyu, three booster packs, and a PTCGO code card.
It’s likely Mimikyu is from the “Sun & Moon Limited-Edition GX Starter Set” that was available at Japanese Toys R Us stores this month.
