How do you reset a used copy of Feudal Kingdom so it can be played as a new game?

Question

Accepted Answer

Turn every card so its serial number is on top, sort the cards from 00 to 138, and put the unnumbered STOP card last. A missing card, a missing sticker or writing on a card makes the deck unplayable, though the publisher notes some workarounds for missing cards.
