Diamond & Pearl marked the fourth generation of Pokémon TCG and introduced the Sinnoh region to collectors in 2007. This foundational set remains significant for establishing design trends that would define the modern era of collecting, with its reverse holo versions offering an appealing alternative to standard prints that many enthusiasts prefer for display. Turtwig, the Grass-type starter from this generation, represents the beginning of countless trainer journeys through Sinnoh. Its artwork captures the charming appeal of early evolutions, making reverse holo versions particularly popular among collectors building complete sets or focusing on starter Pokémon across generations.
