Transfiguration Mask is the fourth Indonesian-exclusive set for the Asian Scarlet & Violet Era of the TCG. It combines the Japanese Crimson Haze and Transformation Mask sets — thus, in terms of set composition, it is practically almost identical to the English Twilight Masquerade expansion. The only differences between the two sets are the order of Trainer cards, the reprint of Switch and Pokémon Catcher (which were replaced in the English release with Cook and Raifort), and the inclusion of the illustration rare prints of Okidogi, Munkidori, and Fezandipiti, which were cut from the English release. Transfiguration Mask releases in Indonesia on May 31, 2024, and each booster pack of Transfiguration Mask contains 5 cards.
Besides being sold in individual boosters and boxes of 30 packs, Transfiguration Mask is also available in 2-pack blisters known as "Special Set" (Indonesian: Set Spesial), which are exclusively sold in Indonesian convenience store chain Indomaret. Each Special Set contains a Holo promo card of Grookey, Clefairy, or Eevee with the Transfiguration Mask logo stamped on the bottom right corner of the artwork. A Collector's Set (Indonesian: Set Kolektor) for Transfiguration Mask is also available for sale at card game stores. The Collector's Set contains 10 booster packs of Transfiguration Mask, a stamped promo card of Chansey, and a card list booklet.
