Lost Thunder

Series: Sun & Moon

Release date: November 2, 2018

Cards: 214 (22 secret)

Set code: SM8

Almost eight years passed between Call of Legends and this expansion with barely a Lost Zone card printed anywhere, and then seventeen of them arrive at once, more than any set had carried before. Seven Prism Star cards come with them, and three are Stadiums, a shape the mechanic had not taken until now: Heat Factory, Life Forest and Thunder Mountain, each of them proof against Item and Supporter effects. Thirteen Pokémon GX run through the set, with Lugia GX at the head of them and Blacephalon GX, Tyranitar GX and Zeraora GX behind. Super-Burst Impact held ninety five numbered cards in Japan where the English list reaches two hundred and fourteen, and two theme decks came with it, Blazing Volcano and Storm Caller. Lugia GX is the card the expansion is known by, and the rainbow prints of Alolan Ninetales GX and Mimikyu GX sit with it. Lost Thunder (SM8) was released on November 2, 2018 in the Sun & Moon series, with 214 cards plus 22 secret rares. Its most expensive card is Mimikyu GX #226 (Secret Rare), at $191.87 (median of 5 sales over 30 days, September 30, 2026). A sealed booster box sells for $1,600.41 (median of 3 sales over 90 days, September 25, 2026).
