Rillaboom

The 2020 Darkness Ablaze Rillaboom is a secret rare Grass-type Pokémon card with 170 HP, evolving from Thwackey, illustrated by 5ban Graphics. Raw near-mint copies trade around $7.55, while a PSA 10 is modelled near $52.55 and a PSA 9 near $25.55. In its original set it is a chase card — roughly a 1-in-1,000 booster pull (modelled, not official). Rillaboom has 10 other printings in the catalogue.
