‘Steam Siege’ Prerelease Promos!

Steam Siege Prerelease Promos

The prerelease promos for Steam Siege have leaked on to social media — they are numbered XY144 through XY147. All four are reprints of the same cards in the set, but with exclusive international artwork (spare Volcanion, which was released in Japan as a promo). Thanks goes to Christian A. for the photo! Each promo will be packaged in one of four decks participants receives to play in the tournament.
