These Trading card sets was available for a limted time (7 days) at the Topps homepage. So it is a very limited print run because only the orders will be printed. Its a little difficult to say how many issues are saled because you can order at every Topps language page and the print run counts differ but the cards are the same.
Every Sets was available after the Chapter comes on air at Disney Plus against spoilers. Perhaps Topps get the images also after the Chapter was on air. You have to order every week, you can't
order the 7 Sets at once. Every Set got 5 Cards.
