Premium Champion Pack PSA 10 Guide
Set History & Release Context
Premium Champion Pack: EX×M×BREAK (プレミアムチャンピオンパック EX×M×BREAK, cp4) released April 16, 2016 as a Japanese tournament-format reprint subset spanning the three core mechanics of the XY BREAK era: Pokemon-EX, M Pokemon-EX and Pokemon BREAK.
The set was structured differently from a standard expansion: every card in the 131-card list was printed as a Reverse Mirror Holofoil with no rarity symbol, and each booster pack contained ten cards instead of the typical five. Its purpose was to give competitive players a single product compiling the most-played XY format staples ahead of the rotation (Bulbapedia accessed 2026-05-09).

Top Chase Cards Explained
Because cp4 has no rarity markers and every card is reverse mirror foil, 'chase' takes a different form here — the most graded and traded cards are the full-foil reprints of Pokemon-EX such as M Sceptile-EX, Hoopa-EX and Beedrill-EX, alongside the Trainer reprints of Brigette and Lysandre.
For PSA 10 collectors the appeal of cp4 lies in the unique reverse mirror foil pattern not present on the original prints, making the cp4 versions the more visually distinctive (and often pricier) variants of staple competitive cards.
Investment Analysis
Cp4's investment thesis is structural scarcity: it was a competitive-format product with a finite Japan-only print run, every card is a foil variant, and supply has been steadily drained as players cracked packs for tournament use. The reverse mirror foil treatment cannot be obtained anywhere else, making cp4 prints the only foil version of certain Trainer cards. Risk: a non-rarity-graded pool means PSA 10 demand is concentrated on a subset of meta-relevant cards.
