A mirror card is the Japanese name for a reverse holo, a common, uncommon or rare card printed with a shiny foil finish. Most mirrors have a plain foil pattern. A few recent sets add special patterns, a Poké Ball and the much rarer Master Ball, which turned these everyday cards into a chase of their own.
How to spot a Master Ball mirror
Tilt the card under a light. On a Poké Ball mirror, small Poké Balls show up across the foil. On a Master Ball mirror the pattern is made of Master Balls instead, with their distinctive shape standing out from the card as it catches the light. The card number and rarity are the same as the regular version, so the pattern is the only thing that tells them apart.
Which sets we stock have them
Terastal Festival has both the Poké Ball and the Master Ball patterns. Its Master Ball mirrors are far scarcer than one per box, roughly one every two or three boxes going by collector reports. None is guaranteed. The Master Ball mirror Umbreon (092/187) is the third most valuable card in the whole set on Japanese market prices in October 2026, ahead of almost every Special Art Rare.
Black Bolt and White Flare carry Poké Ball and Master Ball mirrors too, alongside their Black White Rares. Their Master Ball mirrors are Pokémon from the Unova region, the theme of both sets.
Are they worth keeping?
Most Master Ball mirrors sell for far less than a Special Art Rare, but the popular Pokémon among them can be worth more than their rarity suggests, as the Umbreon shows. Sleeve them as you would any hit. Our guides on checking card prices and Japanese rarities help you work out what you have.
