2022-06-10 : Any enters-the-battlefield abilities of the copied creature will trigger when the token enters the battlefield. Any “as [this creature] enters the battlefield” or “[this creature] enters the battlefield with” abilities of the chosen creature will also work.

2022-06-10 : Except for power and toughness, the token copies exactly what was printed on the original creature and nothing else (unless that permanent is copying something else or it is a token; see below). It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, and so on.

2022-06-10 : If the copied creature has {X} in its mana cost, X is considered to be 0.

2022-06-10 : If the copied creature is a token, the new token that's created copies the original characteristics of that token, with the exceptions noted above.

2022-06-10 : If the copied creature is copying something else, then the token enters the battlefield as whatever that creature copied, with the exceptions noted above.
