This card was included as a Regular card, a Full Art card, and as a Secret card in the Crimson Invasion expansion, first released in the Japanese Awakened Heroes expansion, each with artwork by 5ban Graphics. A reprint featuring the same artwork as the Regular print but with a Shiny version of Silvally was released in Japan as one of the SM-P Promotional cards, available as part of the Sparkling Silvally GET Campaign, which began on September 15, 2017. For every five booster packs purchased in one transaction at participating stores, customers would receive a special pack containing 1 of 13 possible cards, 9 of which comprised standard Sun & Moon Era prints of the basic Energy cards.
The Regular print was reprinted again in the Japanese GX Battle Boost subset, again featuring different artwork by the same artist. The SM-P Promotional print was released in English as one of the SM Black Star Promos, available in the Shiny Silvally-GX Box released November 17, 2017. A Jumbo version was also included in the box. The European Silvally Box, also released November 17, 2017, includes a Jumbo version of the Regular print. The Japanese GX Battle Boost print was later included in the Ultra Prism expansion. The Awakened Heroes Regular print was reprinted again in the Japanese GX Ultra Shiny subset. A Shiny version of the Full Art print was included in the Hidden Fates expansion, which was also included in the GX Ultra Shiny subset.
