Whether you’re a fan of Charmander or Bulbasaur, Turtwig or Piplup, from March to October you’re in for a big treat. To celebrate 25 years of Pokémon, each month select retail partners will release a different pack of three oversize cards depicting the featured region’s three first partner Pokémon. Stay tuned for additional information about where and when these packs will be available.

Since the featured first partner Pokémon will change each month, don’t forget to schedule monthly visits to collect all the promo cards. And in case you’re worried about how best to store these treasured oversize cards, keep an eye out for the First Partner Collector’s Binder, which is big enough to hold them all and comes with an oversize Pikachu card.

Happy collecting!
