By April 2016, the XY era had spent two years running three separate chase mechanics at once — Pokemon-EX, Mega Evolution Pokemon-EX, and Pokemon-BREAK. Premium Champion Pack didn’t add a fourth mechanic. Instead, it put all three onto one shared card finish, doubled the usual pack size, and guaranteed a hit in every single pack — a format built specifically to summarize the era rather than extend it.
This guide covers what CP4 actually is, how its pack structure differs from a standard Japanese booster, and the M Gengar EX single we currently carry graded. If you’re trying to place CP4 inside the wider concept-pack series or the XY era generally, we link out to the guides that cover that ground in full rather than repeating it here.
CP4 “Premium Champion Pack: EX x M x BREAK” released April 16, 2016, with 131 numbered cards plus unnumbered basic energy. We currently list a graded PSA 10 M Gengar EX (049/131) (update: currently sold out — restock requests via Quick Order), currently listed at ¥71,585 — graded singles like this are one-per-listing items, so availability can change quickly.

What Is CP4? Premium Champion Pack Explained
CP4 “Premium Champion Pack: EX x M x BREAK” released in Japan on April 16, 2016, as the second subset of the XY BREAK era. It sits in the same concept-pack lineage as CP2, CP3, CP5, and CP6 — Japanese sets built around a curatorial theme rather than a new block of tournament-legal expansion content, leaning heavily on reprints with some new cards mixed in.
CP4’s theme is a retrospective: it collects Pokemon-EX, Mega Evolution Pokemon-EX, and Pokemon-BREAK — the three headline mechanics that had defined the XY era since 2014 — into a single 131-card checklist (001/131 through 131/131), alongside supporting reprints, plus a run of unnumbered basic energy cards covering all nine basic Energy types plus Double Colorless (Grass, Fire, Water, Lightning, Psychic, Fighting, Metal, Darkness, and Fairy).
Because every card is a reprint or retrospective pull rather than a new mechanic launch, CP4 functions less like a normal expansion and more like a themed sampler of everything the XY BREAK era had already introduced by mid-2016. If you want the full picture of where CP4 sits among CP1 through CP6, our Japanese concept packs guide walks through the whole series side by side.
EX, Mega EX and BREAK in One Set
The three mechanics CP4 draws from each arrived at a different point in the XY era. Pokemon-EX carried over from the Black & White era as the format’s first big power-boost card type — higher HP and stronger attacks in exchange for giving up two Prize cards when knocked out. Mega Evolution Pokemon-EX followed, adding a mid-battle transformation with a matching stat jump on top of the existing EX framework. Pokemon-BREAK arrived last in late 2015 — a landscape, gold-foil card that BREAK Evolves from a standard Pokemon while keeping that Pokemon’s attacks and Abilities.
CP4 pulls cards representing all three mechanics into one checklist rather than launching a new one, which is what makes it read as a summary set of the XY BREAK era’s headline gimmicks rather than a fresh expansion. For a broader look at how EX and Mega EX cards work across the whole era — not just this one set — see our XY-era EX & Mega EX cards guide.
The Anchor Card: M Gengar EX (049/131)
Card 049/131 is M Gengar EX, a Mega Evolution Pokemon-EX that evolves from Gengar-EX, illustrated by 5ban Graphics. Its English structural counterpart is M Gengar-EX from Phantom Forces, card #35 — the same Mega Evolution slotted into the English-language equivalent set. As a Mega Evolution EX, it belongs to the tier CP4 guarantees at least one of per pack, alongside standard EX and BREAK cards, rather than being a rare pull on top of a normal set structure.

Pack Format: 10 Cards, Reverse Mirror Holofoil, Guaranteed Hit
CP4’s physical format sets it apart from a standard Japanese booster in two ways. First, every card in the 131-card run is printed in reverse mirror holofoil, with no separate printed rarity marking — the whole set shares one finish rather than splitting into commons, rares, and holos the way a mainline XY-numbered set does. Second, packs contain 10 cards rather than the usual 5, and each pack is guaranteed at least one Pokemon-EX, BREAK, or Mega Evolution EX card.
That guaranteed-hit structure is part of why CP4 reads more like a curated highlight box than a standard set — every pack opened returns one of the three headline mechanics the set is built around, not just a chance at one buried among commons. It’s the same logic that makes concept packs a distinct category from mainline expansions across the CP1–CP6 series: a denser, more consistent pull rate than a mainline expansion.
CP4 in the Concept Pack Series and the XY BREAK Era
CP4 is one entry in a run of Japanese concept packs — CP1 through CP6 — that released alongside the mainline XY-numbered sets between 2015 and 2016, each built around its own theme rather than new tournament content. Our concept packs guide covers CP1 through CP6 side by side, including where CP4’s EX/Mega EX/BREAK retrospective sits relative to CP6’s later 20th Anniversary retrospective, released roughly five months afterward in September 2016.
Zooming out further, CP4 is one piece of the wider XY era (2013–2016), which introduced Mega Evolution and made EX its defining mechanic before handing off to Sun & Moon’s GX cards in late 2016. Our XY era collector guide maps the full era — mainline sets, concept packs, and 1st Edition context — in one place, which is the fastest way to see how a themed set like CP4 fits against the rest of the timeline.
