This Reverse Holo Rotom (#20/90) is from the 2010 Pokémon HeartGold & SoulSilver “Undaunted” expansion. The card’s vivid art by MAHOU shows Rotom grinning amid starry swirls, and the reverse-holographic foil pattern makes the border and background shimmer under light. As a Lightning-type Basic (60 HP) with the “Mischievous Trick” Poké-Power and “Plasma Arrow” attack, it reflects Undaunted’s clever gameplay style. A Rare card from the HGSS era, it appeals to collectors and players alike as a nostalgic piece of Pokémon TCG history with eye-catching art and a fun prize-switching ability.
