HeartGold & SoulSilver Series

The HeartGold & SoulSilver era, which ran in 2010, celebrated the return to the Johto region. This series is famous for its unique Pokémon LEGEND cards, where players had to combine a top and bottom half to play a single, ultra-powerful Pokémon that gave up two Prize cards.The era also brought back Pokémon Prime, powerful versions of standard Pokémon with alternate art that served as the main chase cards. This series was also notable for reintroducing Basic Darkness and Metal Energy cards (rather than just Special Energy) and ended with the Call of Legends set, which featured a popular "SL" subset of Shiny Pokémon.
