    "Prices are moonstone market data (TCGplayer market for raw copies) pulled August 18, 2026; twelve month moves computed from the same feed's August 18, 2025 points. CORRECTED 2026-09-22: the Umbreon VMAX twelve-month move was published as +2.1% and is +78.3% on that feed, $1,355.20 on August 18, 2025 against $2,416.28 on August 6, 2026, its last reading before publication; the sentence describing it as a card that had gone sideways for a year has been rewritten from the series rather than from memory. The other four twelve-month moves cannot be rechecked: the weekly per-card tape was later overwritten by its own refresh and the series for Umbreon ex SIR, Base Set Charizard, Neo Genesis Lugia and 151 Charizard ex now all begin on August 30, 2026. Their August 2026 prices reproduce within a few percent of the first surviving reading on each. The 30th Celebration entry is a 2026 release. CORRECTED 2026-09-22: its trailing window was excluded rather than annualized, which was right, but the $1,000 quote beside it needed the same treatment and did not get it. The set goes on sale September 16, 2026, four weeks after this piece was written, and our recorded series for that card reads exactly $1,000.00 on every one of the 30 days from August 13 to September 11, the flat presale placeholder our set-lifecycle rule exists to catch. It is quoted here as a presale figure and nothing in the 2031 argument rests on it being a traded price. For the record, the card first moved on September 12 and was $623.99 by September 18. Everything stated about 2031 is prediction, argued from supply, population, and demand mechanics, and labeled as such."
