Team Up is the ninth main expansion of the Sun & Moon Series of the Pokémon Trading Card Game.

They used pokemon from Pokémon: Let’s Go, Pikachu! and Let’s Go, Eevee!, featuring Generation I Pokémon and the Kanto region.

The set contains 196 cards. The list consists of 181 base cards and 15 secret rare cards. This is the first set to include Tag Team Pokemon GX.

Team Up introduced TAG TEAM Pokémon-GX which features two Pokémon that shared at least one type. They are Basic Pokémon cards and have higher HP than regular Pokémon-GX. When a player Knocks Out a TAG TEAM, the opponent takes three Prize cards instead of two. They have a + sign next to the attack’s Energy cost of the GX attack. Extra energy cards can apply more effects than using only what the pokemon require.

There were yellow lines on the top-left and bottom-right corners of the card border. A TAG TEAM label in a yellow bar is below the Stage and the card name. The TAG TEAM rule box took the place of the regular Pokémon-GX rule box. TAG TEAM Pokémon-GX generally came in four types of prints, Regular card, Full Art card, alternate art Full Art card, and Secret Rainbow Rare card.
