Collecting & Where to Buy
XY Steam Siege is out of print and trades on the secondary market. Common singles are inexpensive, while the Pokémon-EX, Full Art and secret rares carry the strongest premiums.
Collector tip: the Full Art and secret cards are the prize — check borders and surface closely on any graded copy.
