Gunk cards are not tokens. Treat Gunk cards just as one would treat regular cards. They can move between zones just like any other card and continue to exist for the duration of the game. At the end of the game, players should make sure to remove all Gunk cards from their deck.

Players can represent Gunk cards using objects from outside the game so long as the game state remains clear and understandable to all players. They might need to get creative.

For many playtest cards, you’ll need to make a generous assumption that basic game rules would be updated to allow them to work. The Mystery Booster 2 Playtest Card Notes section (reproduced here in individual Gatherer rulings) provides guidance for fitting these cards into the existing rules structure.
