As I posted several months ago, the Roaring Skies 3-pack blister comes with either XY49 Regirock or XY50 Pangoro while the 1-pack blister comes with either XY47 Heliolisk or XY48 Meowstic. The blister packs have now been released in stores.
All four promos are printed on galaxy holofoil paper, meaning Regirock is the first English Ancient Trait card to receive this treatment. Isn’t the galaxy holofoil paper better than the regular holopaper they use for the XY holos? :p
