Dragon Frontiers

EX Dragon Frontiers, released in November 2006, is the 31st set of cards in the Pokémon Trading Card Game and the 15th set released by Pokémon USA. Its symbol is a pair of black mountains on a circular white background. It is a set of 101 cards. The set is based on an unknown set of islands far away, inhabited primarily by Dragon Pokémon. This set marks the final appearance of Delta Species Pokémon, and, strangely, almost every single Pokémon card is Delta Species. There are even "Delta Star" Pokémon, Mew and Charizard, whose type depends on their alternate color (Shiny form), which is, in this case, Water and Dark, respectively.

This set introduces a new mechanic: Shockwave and Imprison markers. These markers are similar to special conditions, save that they can be applied to benched Pokémon and that they don't go away when the Pokémon retreats. Only three cards in the set use these markers, however: two Pokémon place the markers, and one Pokémon can remove them.
