The cards were unofficially revealed in a leak last week along with most of the other cards in the set.
The Detective Pikachu mini-set will release through various Detective Pikachu promo products starting April 5th in the U.S. and March 29th in some international countries. Each booster pack will contain four cards; each card in the set is holographic.
