Presumably both cards will be printed on holofoil paper. However, Pikachu was already released as a a holo in the Shining Legends Raichu-GX Premium Collection.
As posted before, the product description states “These decks contain more Pokemon and fewer Trainers with simpler cards for an experience aimed at a younger audience.”
Each package will retail for $12.99 and contain a 60-card deck, a metallic coin, a deck box, damage counters, a 2-player playmat and rule sheet, and a PTCGO code card to play the deck online.
They’ll release on November 30th. They’re clearly intended to introduce young Pokemon fans to the TCG via the Let’s Go hype.
