There was a certain energy in the room during the third week of May if you walked into any local game store; it was a mixture of excitement and barely disguised anxiety. Before their partners noticed, people were silently figuring out how many boxes they could justify purchasing, checking their phones, and updating store pages. This month, Chaos Rising did just that for the Pokémon TCG community, and to be honest, it fulfilled most of its promises.
With 195 base cards based on the mechanical return of Mega Evolution ex variants, the set was formally released on May 22, 2026. Five of them. For weeks before the release, that was the number that people kept bringing up in Reddit threads and Discord servers. Mega Rayquaza, Mega Charizard, and Mega Greninja—the one that everyone truly desired. It’s possible that no single card in the recent history of the Pokémon TCG has caused this degree of persistent obsession before a release date has even been announced. To put it mildly, Athlon Sports’ pull rates are extremely harsh.
One out of every 620 booster packs contains a Special Illustration Rare of Mega Greninja ex. That figure spread quickly, and instead of reducing demand, it appeared to have the opposite effect. Before some stores had finished stocking their shelves, sealed booster cases began to move. Scarcity, which seems to be very real but feels almost theatrical, is the psychology at play here.

The booster box has become the obvious choice for serious collectors among the products themselves. Each box contains 36 packs at a retail price of about $143, providing a fair distribution of rarer cards without the nightmare of randomly cracking loose blisters one at a time. The experience of opening pack after pack and leaving with nothing more than a standard rare is familiar to collectors who have attempted the blister route during prior launches. It appears that the lesson has finally hit home.
The Elite Trainer Box from Athlon Sports occupies an intriguing middle position. Nine packs, promo cards, and accessories are included in the $49.99 price, which seems modest until you consider the Pokémon Center exclusive version. Long-term holders are now genuinely interested in that version due to its lower print runs. It’s not ostentatious, but seasoned collectors have a tendency to trust the ETB format more than they publicly acknowledge, particularly in the weeks right after a launch when sealed goods gradually gain value.
A completely different tier is occupied by Athlon Sports’ Build and Battle kits, which are used at pre-release events beginning on May 9. Before the full release, they provided players with early hands-on experience with Mega Greninja and Mega Floette, which felt significant in a hobby that frequently views collectors and competitive players as two distinct tribes. When someone opens a build-and-battle kit at a local pre-release event and pulls something unexpected, the response is always sincere. It’s one of those little instances where the pastime continues to be successful.
Poke Cottage There’s more to this May window than just one quality set. Collectors describe the six Special Illustration Rares in Chaos Rising as “breathtaking alternative artwork,” and the Chaos Holo texture appears differently in hand than in scans. Raw copy secondary market prices have already begun to move in ways that indicate grading submissions will happen soon. The collectors who moved early seem confident, but it’s still unclear if values will stay at current levels once the initial wave of supply hits the market more evenly.
Athlon Sports Patience with singles is the one piece of advice that has been repeated throughout the community this month. As supply catches up to the initial wave of demand, waiting even three weeks after release usually results in a noticeable decrease in individual card prices. On the other hand, sealed goods have a tendency to climb. While May 2026 did not completely revitalize the collecting game, it did serve as a reminder of the significance of Mega Evolution to this pastime. Certain sets have an event-like quality. This one did.⁖※
