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.
