Steelix #150

This Illustration Rare Steelix from the Mega Evolution set is a highly notable secret rare card, distinguished by its unique artwork and its numbering beyond the standard set total. Its value is primarily driven by its inherent scarcity as a secret rare and the unique appeal of its full-art illustration.

As card 150/132, its number exceeding the set's official total of 132 cards immediately identifies it as a secret rare, making it one of the more challenging cards to obtain from booster packs. The 'Illustration Rare' designation further highlights a unique, often full-art presentation where the artwork covers a significant portion of the card, a feature highly valued by collectors for its aesthetic appeal. This Stage 1 Metal Pokémon boasts 200 HP and features the 'Welcoming Tail' attack, which can deal substantial bonus damage if the player has exactly six Prize cards remaining, adding a strategic dimension to its playability. Steelix's formidable presence is also echoed in its Pokédex description as the "Iron Snake Pokémon," whose body transformed from accumulating iron internally, a characteristic often reflected in its robust card stats.
