The short, expensive tail of the set.
You can own 109 of the 119 priced cards in Xy - Steam Siege for about $114. The median card is $0.29. The remaining $334 sits in just 10 chase cards, and one of them (Gardevoir EX (Secret), $107) is 24% of the entire set on its own. A full set is not one long climb. It is a cheap, fast 24% and then a very short, very expensive tail.

Every price is the tracked TCGplayer figure from our nightly sealed sync. Cost per pack is shown only where the pack count is recorded on a single-unit product; lots (cases, multi-sets) are listed but never enter per-pack math. No pack counts are assumed.
Rip report
No rip report for Xy - Steam Siege
No published pull-rate study exists for this set, so there is nothing honest to simulate. We only rip sets whose per-pack odds come from a published, sourced study, and an inherited or inferred rate would put an invented number under every figure on this panel.
We publish a rip simulation only where per-pack odds come from a published, sourced study. Which sets have published pull rates counts what exists: 31 of the 110 English sets sold in booster packs, resting on eleven studies.
