Sun & Moon is the first main expansion of the Sun & Moon Series of the Pokémon Trading Card Game.

It utilizes the Pokemon from the Pokémon Sun and Moon video games. These are Generation VII Pokémon and the Legendary Pokémon Solgaleo and Lunala.

The trading card set contains 163 cards, including 11 new Pokémon-GX and 40+ Pokémon native to the Alola region.

The English expansion sent buyers to the stores on February 3, 2017.

The booster pack size for English expansions increases from 11 to 12 cards. Each pack included a Basic Energy card.

Sun & Moon introduced Pokémon-GX, a type of Pokémon. Pokémon-GX is a more powerful version of Pokémon. When a player Knocks Out a Pokémon-GX, the opponent takes two Prize cards instead of one. Pokémon-GX has a GX attack which has more powerful damage or effects than usual attacks. Each player could only use one GX attack per game. Pokémon-GX generally came in three types of prints, Regular card, Full Art card, and Secret Rainbow Rare card. The card border was black. They lacked the Pokémon’s Pokédex number, species, height, and weight. The GX attack’s energy cost, name, and damage are in a blue and black bar with a silver border. The Pokémon-GX rule box took the place of the Pokédex entry. Regular prints featured the artwork covering most of the card with the Pokémon out of the card border. The whole card was Holofoil and had a glossy finish. Full Art prints have a shard-like diamond background. Rainbow Rare prints have the same artwork as Full Art prints but were fully silver (including the Pokémon) and have a rainbow reflector finish.

Sun & Moon also introduced an updated card design, which included numerous changes. The Stage and Evolution area received new graphics. The curvy strips between the Pokémon’s name and the HP are gone. The bar displaying the Pokémon’s Pokédex number, species, height, and weight also received a new graphic. The background of the card text area featured a new design. The Weakness and Resistance are in a white bar and the retreat is in a separate white bar beside the other two. The Pokédex entry is without a frame. The illustrator’s name, set symbol, card number, and card rarity are to the left, above the copyright information. The Sheen Holofoil changes to Water Web Holofoil. The Reverse Holofoil also received a new design.
