Chaos Rising (ME04) SIR reportedly 1.21% per booster, or 1 in 83
Pull rates for the English Chaos Rising (ME04) booster have been reported from a TCGplayer study of more than 8,500 boosters, which puts a Special Illustration Rare at 1.21% (about 1 in 83) per booster. A Double Rare is 20.30%, an Illustration Rare 10.66%, an Ultra Rare 8.29% and a Mega Hyper Rare 0.10% (about 1 in 1,000). These are not official publisher rates, and the sites repeating them (Cardlytics, Godpack and SetPulls) all trace back to the same study, so they are not independent confirmations. The original TCGplayer page could not be read directly because it required JavaScript, and no large independent French sample was identified, so the figures are not certified French rates. Japanese boosters may also differ in composition and distribution, so these rates do not apply automatically to them.
Mega Greninja ex (French name Méga-Amphinobi-ex) appears in Chaos Rising as card 116/086, a Special Illustration Rare, and as card 122/086, a Mega Hyper Rare. Godpack reports a Mega Hyper Rare ratio of 1 in 956, while Cardlytics and SetPulls use 1 in 1,000, derived from the rounded percentage.
Assuming 6 equally likely SIRs, one specific SIR works out to about 1 in 496 per booster. That is a calculation by the source, not a measured rate. At a 1.21% rate with independent boosters, the chance of at least one SIR is about 1.2% with 1 booster, 3.6% with 3, 7.0% with 6, 10.4% with 9, 19.7% with 18 and 35.5% with 36. For one specific SIR, again assuming 6 equal SIRs, the chance is about 0.2% with 1 booster, 0.6% with 3, 1.2% with 6, 1.8% with 9, 3.6% with 18 and 7.0% with 36.
For comparison, the ME05 set (French name Nuit Noire) has an SIR rate of 1.25% against 1.21% for ME04, but the source says this alone does not show that one product is more generous. The French Chaos Ascendant formats listed by the retailer are the blister, the TriPack (three boosters), the ETB (nine boosters plus accessories) and the display (36 boosters). No format has been shown to give better per-booster odds.
