Tag All Stars is a subset in the Pokémon Card Game Sun & Moon Era in Japan. It was released on October 4, 2019. Tag All Stars acted as a retrospective of the Tag Team block of the Sun & Moon Era. As such, it contained a large amount of reprinted cards from around this period, featuring the focal Tag Teams from the Tag Bolt, Double Blaze, and Miracle Twin expansions, and Night Unison, Full Metal Wall, GG End, and Sky Legend subsets, as well as other popular Pokémon-GX cards. Several Pokémon included in the subset featured artwork previously unavailable in Japan.
Much like the preceding High Class Pack GX Ultra Shiny, Tag All Stars included a large amount of Secret cards—53 in total—among which include Full Art and Rainbow Rare versions of Pokémon-GX that received only Regular prints in standalone products, Full Art versions of previously-released Trainer cards, and embossed Holofoil versions of the basic Energy cards. The seven focal Tag Teams from previous expansions and subsets also received gold Ultra-Rare prints for a total of 226 cards. Tag All Stars also had a parallel foil set—each card without a rarity symbol featured a Mirror Holofoil variant. Combined with the standard set and nine generic basic Energy cards, this created a master set of 369 cards.
Each pack contained eleven cards instead of five, including one guaranteed Pokémon-GX card, two Holofoil cards, one Energy card, and one parallel foil card. Energy cards were always Mirror Holofoil unless a pack included a Super-Rare version of one. Approximately 1 out of every 250 packs may contain 10 Super-Rare cards in addition to the Energy card, colloquially referred to as "god packs" in other TCG circles, and a first for the Pokémon TCG in Japan.
All Pokémon that debuted in Tag All Stars were localized and released in the Cosmic Eclipse expansion, as well as the two new TAG TEAM Supporter cards.
