The Lillie's Resolve and Lillie's Full Power cards from the Mega Brave Dream League set hold significant appeal for Pokémon collectors, particularly due to Lillie's prominence in the Sun & Moon series, aired in 2016.

As a character central to the story, her cards have garnered interest not only for their artwork but also for their representation in competitive play.

This PSA 10 grading indicates exceptional preservation, a crucial factor given the often fragile nature of trading cards and the high standards of collectors in the Japanese market.

With limited production runs associated with themed sets like this, outstanding condition examples such as this set are increasingly rarer, further elevating their collectability.
