Marshadow #146

The Marshadow card 146/132 from the Mega Evolution set is a notable Secret Rare, distinguished by its Illustration Rare designation. Its status as a Secret Rare, indicated by a card number exceeding the set's official total of 132, inherently contributes to its collector appeal due to a lower pull rate. The Illustration Rare rarity further enhances its value, signifying a special artistic presentation of the Pokémon that sets it apart from standard prints.

As a Basic Fighting-type Pokémon with 90 HP, Marshadow features the signature attack "Shadowy Side Kick." This attack offers a powerful strategic advantage: if it Knocks Out an opponent's Pokémon, Marshadow becomes immune to all damage and effects of attacks during the opponent's next turn. This unique defensive capability, combined with its elusive nature as the "Gloomdweller Pokémon" — described in its Pokédex entry as "Able to conceal itself in shadows, it never appears before humans, so its very existence was the stuff of myth" — makes this card distinct both mechanically and thematically.
