Rillaboom

Rillaboom is a Grass-type Pokemon card from the 2021 Shining Fates set, which was a popular special set featuring shiny Pokemon variants. As a standard rare of a starter evolution, it has moderate appeal among collectors but faces significant supply from the heavily-opened set. Prices have been declining sharply, with the card showing a 54.5% drop over the past month as market values correct toward bulk pricing levels.
