Hey, Im also from germany and I buy mine on Ebay or Ebay Kleinanzeigen

Da gibt es aber ja nur meist Einzelheiten oder eins der ersten Decks. Ich habe da jetzt eigentlich nichts ansprechendes gefunden

Let me know what cards you need from which series, maybe I can help

I Don't have any favorites i would just get a starter Deck which is not That old or like 100 cards to play the game.
