What Chaos Rising actually is

Chaos Rising shipped on May 22, 2026 as the back-half companion to the year's Mega Evolution arc. The set runs 122 numbered cards before secret-rare extensions, leans hard on the Mega Evolution mechanic the format adopted in late 2025, and finally puts a long-rumored Mega Greninja ex on cardboard for the first time.

If you've been opening 2026 product, the structure will feel familiar. You still get the Mega Attack Rare treatment, you still get the textured chase slots in the back third, and pack distribution still funnels chase pulls into the bonus 11th and 12th card slots that the format moved to last year. The change is mostly the cast.

The top chase cards

The headline pulls everyone is watching:

1. Mega Greninja ex (Special Illustration) — Long-time fan favorite, first proper TCG appearance in this rarity tier. Demand is shaped less by play and more by the character's standing.
2. Mega Greninja ex (Hyper Rare) — Gold-etch treatment. Smaller print pool than the SIR, but historically gold variants soften 30–60 days after launch.
3. AZ (Full Art Supporter) — The XY-era trainer returning as a full-art is the sleeper of the set. Lore-heavy collectors are stacking these.
4. Mega Aerodactyl ex (SIR) — Strong art, niche playability, modest print share.
5. Mega Pidgeot ex (SIR) — Carries momentum from the Mega Evolution arc.
6. Mega Tyranitar ex (Hyper Rare) — Dark-type collectors push this regardless of meta.
7. Iono's Bellibolt ex (SIR) — Trainer-gallery cards keep outperforming raw chase pulls in 2026.
8. Mega Greninja ex (Ultra Rare) — Lower ceiling, but the entry point if you just want the card.
9. Hop's Cinderace ex (SIR) — Riding the Galar nostalgia wave.
10. Mega Heracross ex (Full Art) — Quietly underprinted compared to the rest.

Where prices will probably go

Launch-week pricing on Mega ex SIRs has followed a fairly consistent curve through the 2026 arc: a 7–10 day spike, a 30-day cool-off of roughly 30–40 percent, then a slow climb if the character has lasting demand. Greninja almost certainly belongs in the "lasting demand" bucket. Aerodactyl and Heracross probably don't, which is exactly why they're interesting at the cool-off floor.

Sealed vs. singles

Booster boxes of Chaos Rising are tracking similar to Phantasmal Flames at the same point in its cycle. If history rhymes, the sealed product floor lands roughly six weeks after release, then drifts up as ETBs disappear from retail. If you want exposure without committing to specific cards, sealed boxes are the cleaner trade.

How to play it

For most collectors the simple play is: open enough product to enjoy the set, complete the master set through singles instead of more boxes, and treat the Greninja SIR as the single card you actually chase. Everything else in the top 10 has room to fall.
