About Ultra Ball
Market context, fair-value analysis, and investment signals.
Ultra Ball (#186) is a secret rare from the Brilliant Stars set in the Sword & Shield series, released February 2022, illustrated by sadaji. Its secondary-market behaviour is worth watching if you care about Pokemon TCG valuation.
The current market price sits at £15.29, while our model's fair-value estimate comes in at £8.78. That puts the card 74.2% above where the fundamentals suggest it should trade, which is why we label it as steeply overvalued. The model is trading well above our fair-value estimate, and unless the underlying drivers change the gap tends to close over time.
TCGPredict's fair value estimate is built from the same fundamentals a serious collector would weigh up: pull-rate rarity, character premium, artwork desirability, universal appeal, and the print-run dynamics of the parent set. The breakdown further down this page shows exactly how each of those factors is scored for Ultra Ball, so you can judge whether the model's view lines up with yours before you buy, sell, or hold.
If you're researching Ultra Ball for investment or portfolio tracking, it's worth comparing it against the rest of Brilliant Stars and against other secret rare cards in the same price band.
