Master Ball Pattern
Master Ball pattern (noun): the rarest reverse-holo variant in Pokémon's Prismatic Evolutions set — the card's foil background printed in a repeating Master Ball design, far scarcer than the standard or Poké Ball reverse patterns.
Master Ball Patterns in More Detail
Prismatic Evolutions replaced some standard reverse holos with two special patterns: Poké Ball (more common) and Master Ball (the chase tier). Every card in the set can exist in both patterns, so pattern collectors chase full Master Ball sets — and Master Ball versions of stars like Umbreon carry dramatic premiums over their regular reverses.
The format traces to Japan's 151 set, and it stacks with the set's other chase mechanics — SIRs and god packs — to make Prismatic Evolutions one of the most chase-dense products ever printed.
