Do reverse holos count in a master set?
Yes.
Reverse holos are the main difference between a master set and a complete set, and nearly every master-set collector counts them.
A reverse holo has the foil on the card itself rather than on the artwork. They first appeared in Legendary Collection (2002), so earlier sets don’t have them. Since then, most expansions print a reverse holo of each common, uncommon and rare, while ultra rares (ex, V, VMAX, full arts) and secret rares usually don’t get one.
A few recent sets print more than one reverse pattern of the same card. Prismatic Evolutions has Poké Ball and Master Ball versions alongside its standard reverse holos, and a master set counts each pattern as a card of its own.
