The May 2026 Mega Evolution release built around Mega Greninja ex and the new Chaos Holo SIR texture. Here's the full breakdown — the chase cards, the rarity tiers, the pull-rate math, and whether ripping a box makes sense at current secondary prices.
Chaos Rising's value is concentrated in Mega Greninja ex and a handful of Chaos Holo SIRs. The Chaos Holo texture is exclusive to this launch — a scarcity angle later reprints won't carry. Verify all prices against current sold comps.

What makes Chaos Rising distinct is the Chaos Holo texture — a launch-exclusive finish on the set's six SIRs. Here's how the rarity tiers stack up.
Mega Greninja ex hits roughly 1 in 1,786 packs. At ~36 packs a box and ~$307 secondary, the statistical cost to pull the Greninja SIR runs into the thousands — which is exactly why singles beat sealed for the chase. Booster boxes are a fun rip and a set-build, not an EV play. Run your own scenario with the calculator.
MSRP if you can get it; otherwise weigh secondary against just buying the card.
