The theme of Strength Expansion Pack: Incandescent Arcana revolves around beautiful and strong Pokémon, featuring the likes of Alolan Vulpix, Reshiram, and Serperior. Alolan Vulpix is one of the focal Pokémon, supporting the Pokémon V mechanic, as well as the Pokémon VSTAR mechanic—the first unevolved Pokémon to do so. In line with the previous two Strength Expansion Packs, Incandescent Arcana includes another selection of Character Rare Full Art cards and Radiant Pokémon. Common and uncommon cards once again have Mirror Holofoil variants featuring a Poké Ball pattern. Each booster pack contains six cards, two of which are guaranteed to be Holofoil.
