Pokémon TCG Pocket Leak Hints at High Class Pack EX Miniset
Rumored September Miniset May Re-Release A-Series Cards with a New Pack Structure
A new leak may have revealed the next Pokémon TCG Pocket miniset, tentatively titled High Class Pack EX, and it looks like this expansion will take a very different approach to card distribution. Many fans already suspected that the A4b set would be the final chapter of the A-series, and this leak seems to confirm it.

A Surprise Reveal
According to reports, the official Japanese Pokémon TCG Pocket account briefly posted (and quickly deleted) a teaser trailer for the upcoming miniset. The trailer pointed to a September 30 release date and the title High Class Pack EX (a direct translation of the Japanese name, which may differ in English).

A Set for Catching Up
Unlike past expansions, this set may not feature any brand-new cards. Instead, it’s rumored to re-release cards from the A-series, some with updated artwork. This could give players a much-needed chance to fill in gaps in their collections before the game transitions into the B-series era.

New Pack Structure
Another big change: booster packs for this set reportedly contain just four cards instead of five. The twist? One of those cards is guaranteed to be an EX or four-diamond rarity, which ties directly into the “High Class” name. This marks an interesting shift, especially since six-card packs were only just introduced not long ago.

What This Means for the Future
The leak has reignited debate about the future of competitive play in Pokémon TCG Pocket. Some fans believe the High Class Pack EX is a way to help players complete their A-series collections before these cards rotate out of certain PvP formats, like ranked battles. Others argue it’s too early for any kind of rotation, especially compared to the physical Pokémon TCG, which usually keeps cards legal for several years.

Regardless of what’s ahead, if the leak holds true, High Class Pack EX looks like a must-have set for collectors who want to wrap up their A-series decks before the next era begins.
