Today, The Pokémon Company International launched Sword & Shield—Lost Origin, the latest expansion for the hit Pokémon Trading Card Game, at participating retailers worldwide.
Sword & Shield—Lost Origin marks the return of the Lost Zone gameplay mechanic, which is similar to the discard pile but prohibits Trainers from recovering cards during matches. Sword & Shield—Lost Origin also includes Lost Zone cards, three new Radiant Pokémon, and Pokémon VSTAR cards featuring Hisuian Pokémon.
Sword & Shield—Lost Origin is available in booster packs, Elite Trainer Boxes and special collections at Pokémon Center in the US, Canada and UK, as well as other participating retailers.

I wish pokemon silver could be played on smart phones. My 3ds broke and pokemon go bores me. I also can’t trust emulators because I might get a virus.
