- Front: Sirfetch'd, Galarian Rapidash, Porygon, Carapthor

- Back: Blissey, Carapthor, Espeon, Glaceon, Hitmontop, Kleavor, Lickilicky, Magnezone, Melmetal, Galarian Moltres, Mr. Rime, Perrserker, Pupal, Rhyperior, Sandy Shocks, Scream Tail, Galarian Slowbro, Paldean Tauros Combat Breed, Toedscool, and Umbreon

(also some minor text fixes, notably adding Dr. Lava to the credits)

Thanks Albatross for being a total legend :3
