Nivi City Gym (Japanese: ニビシティジム タケシ Nivi City Gym Takeshi) is a Japanese-exclusive Standard Deck that complements the Leaders' Stadium expansion of the Pokémon Trading Card Game.
Unlike traditional Standard Decks which contain 60 fixed cards, this deck has 64. The majority of these cards could not be found in the main expansion. Those that were not were added to the main set when the English version was made. The contents of this deck also provided the basis for the English Brock Theme Deck. The cards Brock's Onix, Brock's Rhyhorn, Brock's Sandslash and Brock's Zubat are four of the notorious "common rares" featured in Gym Heroes, brought about from their fixed rarity in this deck.
Like others, the Nivi City Gym Deck also includes a rulebook, damage counters, status counters, and a custom coin.
