Data Chaos Rising Day-1 Watchlist: 12 Cards to Track

Chaos Rising dropped yesterday (May 22, 2026). The set has 122 cards, a generous pull rate from early Reddit reports, and a clear headline chase: Mega Greninja ex at #122, the Mega Hyper Rare, already trading around $440 in the first 24 to 36 hours.

Here are the 12 cards we'd actually be watching over the next 30 days, with Day-1 reference prices from community-reported eBay and Cardmarket data, and a Buy / Watch / Wait verdict on each.

Key takeaways

• Mega Greninja ex #122 (Mega Hyper Rare) is the headline chase. Day-1 prices landing around $440 (£350) on Cardmarket and eBay sold listings.
• The full Greninja line matters here. Mega Greninja appears as Ultra Rare (#100), SIR (#116), and Mega Hyper Rare (#122). Pre-evolutions Froakie (#88) and Frogadier (#89) are the safest Illustration Rare picks because master-setters are buying.
• Three SIRs are running about $75 to $107 day-of-release: Mega Dragalge ex ($107), Cinccino ex ($107), Mega Floette ex ($75). These typically dip 20 to 30 percent over the next 30 days.
• Trainer SIRs (AZ's Tranquility, Roxie's Performance) have a longer hype tail than Pokemon SIRs because the buyer base is narrower (character fans). Hold off until late June.
• Sealed product is currently 30 to 50 percent above MSRP. ETBs are trading near $80 on OfferUp vs the $54.99 MSRP. The math favors waiting on sealed.
• Of the 12 watchlist cards: 3 Buy, 6 Watch, 3 Wait. The Buys cluster around Greninja line completion (Froakie, Frogadier, Ultra Rare Mega Greninja).

The Mega Greninja headline

Every set release has one card that defines the launch window. For Chaos Rising it's Mega Greninja ex #122, the lone Mega Hyper Rare in the set.

The card has been trading around £350 ($440) on Cardmarket and eBay sold listings in the first 24 to 36 hours after release. A "gold" variant (still being clarified by the community, likely a gold-etched secret) is reportedly fetching £300.

For reference, the Mega Hyper Rare from the previous Mega Evolution-era set (Perfect Order, March 2026) launched around $380 and settled near $250 within 30 days. If Mega Greninja follows the same trajectory, expect $300 to $350 by mid-June.

That's why our verdict on #122 itself is Wait. The card is great. The price is at peak hype. The math on holding off 2 to 4 weeks is straightforward.

The 12-card watchlist

WAIT Mega Hyper Rare

Mega Greninja ex #122

Day-1: ~$440

Reported on Cardmarket and eBay sold listings 24 to 36 hours after release.

The headline chase. Day-1 hype = peak price. Mega Hyper Rare chase cards from prior Mega Evolution sets settled 20 to 35 percent below their launch peak by day 30 as boxes ripped and supply hit secondary. Buying right now means buying at the top of the curve.

WATCH Special Illustration Rare

Mega Greninja ex #116

Day-1: Premium

Multiple Reddit threads call this the 'second chase' people are master-setting around.

Collectors completing the Greninja line need this. The SIR variant is a chase but more pullable than the Mega Hyper Rare, so price typically softens 15 to 25 percent in the first month. Watch for a clean centering listing in the $150 range as the buy signal.

WATCH Special Illustration Rare

Mega Dragalge ex #118

Day-1: ~$107

Reddit-reported Cardmarket asks of £85 in the first 24 hours.

Dragalge is a fan favorite Pokemon design and the Mega evolution is a strong illustration. Mid-tier SIR pricing tends to be the most volatile because supply is meaningful but demand is real. Expect a 20 to 30 percent dip by day 30, then stabilization.

WATCH Special Illustration Rare

Cinccino ex #119

Day-1: ~$107

Same Reddit thread reported £85 day-of-release on Cardmarket.

Cinccino is a regulation-rotation favorite for competitive play and the SIR art is striking. Tournament demand can keep this card's floor higher than the Pokemon-design-only SIRs. Worth watching once competitive deck lists settle in the next 30 days.

WATCH Special Illustration Rare

Mega Floette ex #117

Day-1: ~$75

Cardmarket asks at £60 in first-day Reddit reports.

The cheapest of the Mega ex SIRs and arguably the prettiest. Floette has cross-generation fan demand (Floette is the rare-flower mid-evolution that's beloved by collectors). Watch for a settling price near $60 by day 30 as the perfect buy point.

BUY Ultra Rare

Mega Greninja ex #100

Day-1: $30 to $45

Estimated from comparable Ultra Rare Mega ex base cards in prior sets.

The base Ultra Rare Mega Greninja is the master-set check-box card. Every Greninja-line collector needs one and the price floor tends to settle within 30 days. At Day-1 pricing this is the most undervalued card relative to where it'll be by year-end.

WATCH Ultra Rare

Mega Pyroar ex #99

Day-1: $25 to $40

Ultra Rare Mega ex estimate.

Pyroar is a niche-favorite Pokemon and the Mega evolution debut in Chaos Rising. Card lacks a SIR variant in this set which can sometimes push the Ultra Rare base into the chase-tier-of-the-poor-man slot. Watch the secondary market over the next 30 days.

WAIT Special Illustration Rare

AZ's Tranquility #120

Day-1: Premium trainer SIR

Trainer SIRs in prior Mega Evolution sets launched around $80 to $150.

AZ is a beloved XY-era character and this is his first full-art SIR in years. Trainer SIRs typically run a different price curve than Pokemon SIRs because the audience is narrower (story / character fans), so launch hype can sustain longer. Wait for the next 2 to 3 weeks to see whether this settles or sticks.

WAIT Special Illustration Rare

Roxie's Performance #121

Day-1: Premium trainer SIR

Estimated from comparable trainer SIRs in Perfect Order.

Roxie is a fan-favorite Black/White-era gym leader. The Performance subtitle and the punk-rock styling on Roxie's character SIRs tend to do well with crossover collectors. Same logic as AZ: trainer SIRs can hold premium longer than Pokemon SIRs.

BUY Illustration Rare

Froakie #88

Day-1: $5 to $10

Illustration Rare baseline from prior Mega Evolution sets.

Greninja's stage-1 pre-evolution. Master-set demand for the Greninja line will push this card faster than typical IRs. The IR floor on starter Pokemon in their Mega-set printing tends to settle 30 to 50 percent above launch within 90 days. This is the safest IR pick of the set.

BUY Illustration Rare

Frogadier #89

Day-1: $5 to $10

IR baseline.

Same logic as Froakie. Stage-2 Greninja pre-evolution. Anyone master-setting the Greninja line needs the full chain. Frogadier IRs in particular get less printer love so the print run is effectively thinner per pack than starter IRs. Buy now if you find a clean one.

WATCH Illustration Rare

Xerneas #91

Day-1: $8 to $15

Legendary-Pokemon IRs from prior Mega-era sets.

Xerneas is a Kalos legendary tied to the X / Y story arc that Chaos Rising leans into. Legendary IRs hold value better than common-Pokemon IRs because they appeal to both master-setters and standalone collectors. Watch for the next 30 days to see whether this settles near the $10 floor or pushes higher.

What to buy now

Three cards are in the "Buy now if you find a clean one" category.

• Froakie #88 (IR) and Frogadier #89 (IR). Greninja pre-evolutions. Master-set demand is the most stable price signal in this set. The IR floor on starter-line pre-evolutions tends to settle 30 to 50 percent above launch within 90 days, so paying $5 to $10 now beats paying $12 to $18 in October.
• Mega Greninja ex #100 (Ultra Rare). The base Ultra Rare version that every Greninja-line master-setter needs. Ultra Rares of Mega-set headliners are systematically underpriced in the first month because attention is on the chase variants. Day-1 pricing of $30 to $45 is structurally low.

What to wait on

Three cards we'd hold off on for at least 2 to 4 weeks.

• Mega Greninja ex #122 (Mega Hyper Rare) at $440. Day-1 = peak. Comparable chase cards from prior Mega Evolution sets settled 20 to 35 percent below their launch peak by day 30. Buying now means buying at the top of the curve.
• AZ's Tranquility #120 (SIR trainer). Trainer SIRs run a slower hype-decay curve because the audience is narrower. Wait for the 2-to-3-week point to see whether this sticks at launch pricing or eases.
• Roxie's Performance #121 (SIR trainer). Same trainer-SIR logic. Roxie is a fan-favorite gym leader and the punk-rock styling is striking, but the buyer pool is character-fans, not Pokemon-completion-collectors.

Methodology

This watchlist was assembled on Day-2 (May 23, 2026) and pulls from three signals:

1. Set composition from pokemontcg.io's me4 endpoint, ingested into Catchinary's ec_cards table after Day-1. All 122 cards from the printed set plus secret-rare extensions are loaded.
2. Community price reports from r/PokemonTCG, r/PokemonInvesting, and r/pkmntcgcollections threads from the 48 hours after release. Where specific dollar or pound figures are quoted, they're noted in the price-note column above.
3. Historical baselines from prior Mega Evolution-era set releases (Mega Evolution OG, Ascended Heroes, Perfect Order). Day-1 vs Day-30 trajectories on chase cards from those sets inform the verdict framework here.
