Undone Seal

Series: ADV

Release date: January 16, 2004

Cards: 83

Set code: UNS

Regirock, Regice and Registeel each arrive as a Pokémon-ex, and three Ancient Technical Machine Trainers are printed to match them, one for Ice, one for Rock and one for Steel. The numbering then ends on six Stadium cards in a row, three of them the Hoenn chambers where the golems sleep. Nine Pokémon-ex sit in the list altogether, with Kyogre, Groudon, Metagross, Ninetales, Vileplume and Wigglytuff beside the trio. The publisher's announcement pushed two oddities to the front, an Exploud with four attacks and a Castform with an unusual Poké-POWER. Steven's Advice is the only Supporter, and every card in the Trainer block is Uncommon. Packs held eleven cards with one holo guaranteed, the format the four numbered ADV expansions used. Undone Seal (UNS) was released on January 16, 2004 in the ADV series, with 83 cards. Its most expensive card is Regice ex #38 (Rare Holo ex), at $96.69 (median of 5 sales over 90 days, October 1, 2026).
