Steam Siege is a Pokémon set released 2016/08/03. This page tracks whether its sealed products are worth opening: live TCGPlayer market prices for every product, the expected value of the cards inside, and the pull-rate model behind the math.
XY-era pack (10 cards): a reverse holo, and a rare slot where Pokémon-EX land roughly 1 in 8 packs, full arts about 1 in 30 and secret rares about 1 in 70, with BREAK evolutions about 1 in 13. Vintage sealed: prices are collector premiums, so rip margins are deeply negative by design — the singles market is the real signal, and pokemontcg.io prices it. Elite Trainer Boxes of this era hold 8 packs. Pull rates are community estimates.
