Near Mint condition, current market prices. Includes every card in the set: base printings, reverse holos, and secret rares.

Steam Siege is an XY-era set from August 2016 that introduced powerful Mega Evolution mechanics and established several competitive staples that remain relevant today. The set features iconic cards like Gardevoir-EX and Volcanion-EX, which have driven sustained collector demand nearly a decade after release. As an older XY set with a relatively small card pool (116 cards), Steam Siege maintains strong secondary market prices due to limited supply and enduring playability nostalgia.

Investment Outlook Neutral While Gardevoir-EX commands premium prices, the set's age and the potential for future reprints in special collections limit significant appreciation potential.

Reprint Risk Medium Popular cards like Gardevoir-EX and Professor Sycamore have been reprinted in various special sets and boxes, though full-art secret rares remain scarce.
