2019-11-12 : A Gunk token card is a colorless Gunk sorcery named Gunk with cycling {4}. It has no mana cost, so you can’t normally cast it. It has no spell abilities, so if you do find a way to cast it, it won’t have any effect.

2019-11-12 : Cycling {4} means “{4}, Discard this card: Draw a card.”

2019-11-12 : For effects that look for or modify the creation of tokens, creating token cards isn’t the same as creating tokens.

2019-11-12 : If a token card is put into a hidden zone, you must use a supplementary token card with a Magic card back to represent it. Since these don’t exist yet, you may need to be creative.

2019-11-12 : Unlike a normal token, a token card doesn’t cease to exist in a zone other than the battlefield. It’s both a token and a card. It can move between zones any number of times and continues to exist for the rest of the game.
