If you have been collecting Pokémon TCG: Sword & Shield – Evolving Skies, you may have noticed that while every Eeveelution gets a VMAX, not every Eeveelution gets a standard Pokémon-V. This is because the Flareon V, Vaporeon V, and Jolteon V from the set have been pulled out of Evolving Skies and repurposed as SWSH Black Star Promos. These promo cards are only available in these new Eevee Evolution Tins, which makes them highly desirable items.
Each of these tins comes with four packs in addition to the promo card. You'll get:
One pack of Sword & Shield – Evolving Skies
One pack of Sword & Shield – Chilling Reign
One pack of Sword & Shield – Battle Styles
One pack of Sword & Shield base
So basically, you get one of each of the three most recent sets and one of the set that kicked off the era. This isn't a bad selection of Pokémon TCG sets by any means, and three of these sets (Evolving Skies, Chilling Reign, and the underrated Battle Styles) all give collectors a chance at pulling an Alternate Art.
