#168 Underground Expedition - Celestial Storm (sm7)

Underground Expedition is a Trainer card from the Sun & Moon series, part of the Celestial Storm set released on August 3, 2018. Designed by artist Kagemaru Himeno, it is classified as a Rare Ultra card. The card’s rules specify two primary effects: first, the player looks at the bottom four cards of their deck and places two into their hand, shuffling the remaining cards back into the deck. Second, it restricts the player to playing only one Supporter card during their turn before their attack. These mechanics emphasize deck manipulation and turn management strategies. The card’s supertype is Trainer, indicating it serves as a support card rather than a Pokémon or Energy. Its absence of types, resistances, weaknesses, or attacks aligns with its role as a specialized Trainer card. The card’s design and function are consistent with the Sun & Moon series’ focus on exploration and adventure themes.
