The four decks coming back are "Devour for Power" (helmed by The Mimeoplasm), "Built from Scratch" (the Daretti, Scrap Savant deck), "Wade into Battle" (with Kalemne, Disciple of Iroas leading the charge), and "Breed Lethality" (with everyone's favorite proliferator, Atraxa, Praetors' Voice)

The icy blue color palette is beautifully rendered in the textured Galarian Gallery format, and the card's value is propped up by the dedicated army of Eeveelution collectors who chase every version of every Eevee evolution
