EX Power Keepers is the sixteenth Pokémon Trading Card Game set released by Pokémon USA. It also the first set since EX Emerald to be released only outside of Japan, and the first since EX Unseen Forces not to include Delta Species Pokémon. The set is based on the Hoenn Elite Four as seen in Pokémon Ruby, Sapphire and Emerald, as all four members (Drake, Glacia, Phoebe and Sidney) and the first Champion (Steven) have their own Stadium cards and Pokémon. The set also consists of several reprints of cards from older sets, and is the last third-generation set.
