Blissey

The 2013 XY Black Star Promos Blissey is a promo Colorless-type Pokémon card with 120 HP, evolving from Chansey, illustrated by Akira Komayama. Raw near-mint copies trade around $5.30, while a PSA 10 is modelled near $50.30 and a PSA 9 near $23.30. In its original set it is a chase card — roughly a 1-in-332 booster pull (modelled, not official). Blissey has 12 other printings in the catalogue.
