Cards and rarities

HS Undaunted has 91 cards. Every card shows its number over the printed total along the bottom, as in "4/90". The cards print a set symbol, not a set code; the code here is the short one the catalog and TurnZero HQ file the set under.

Rare Secret1Numbered above the printed total.

The printed total is 90. The four LEGEND cards are two pairs of halves. Alph Lithograph, numbered THREE, is the one secret rare. Set completion in TurnZero HQ counts a set against its printed total and keeps the secret rares apart, so finishing the main set and chasing the cards above it read as two separate goals.

What a complete set costs

One copy of every card in HS Undaunted, bought as singles, cost $4,259.51 on October 22, 2026. That is the second most expensive of the five sets in the HeartGold & SoulSilver series.

Complete set $4,259.51
Main set, 1 to 90 $4,102.62
1 secret rare $156.89
Top three cards $1,866.83 (44%)

The three most valuable cards, Umbreon and two Rayquaza & Deoxys LEGEND cards, come to $1,866.83, or 44% of the total. Without them the set costs $2,392.68. Of the 91 cards, 50 were under $2.00, together $32.59; the other 41 add up to $4,226.92.

Each card is counted at its cheapest priced variant, usually a Normal copy rather than a Reverse Holofoil, or a stamped promo copy where the catalog prices one lower, at its TCGplayer market price. This is what it costs to buy the set as singles. It is not what opening packs returns, and not what a complete set would sell for, which after fees and the many cards worth cents would be noticeably less.

Playing it

The catalog marks every card in HS Undaunted as legal in neither Standard nor Expanded, the two formats Play! Pokémon sanctions. Expanded starts with the Black & White series in 2011.
