Sky Ruler was released on November 22, 2019 in Thailand, followed by a release in Indonesia on March 10, 2020. This set is mainly composed of cards sourced from the dual Japanese Ultra Sun and Ultra Moon expansions, the Forbidden Light, Sky-Splitting Charisma, and Super-Burst Impact expansions, plus some SM-P Promotional cards and those from Japanese subsets. It is split into two sets, Set A and Set B, each of which focuses on specific types. Set A features Grass, Lightning, Psychic, Darkness, and Dragon-type Pokémon, while Set B features Fire, Water, Fighting, Metal, and Fairy Pokémon. The Thai set has an accompanying random GX Starter Deck as it did in the first Asian set after featuring fixed decks in the previous two sets. The Indonesian set also has a companion random GX Starter Deck, which has a different selection of cards to that of the Thai version.
