2023-10-13 : 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.

2023-10-13 : Except for its name and types, 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.

2023-10-13 : If the copied creature has {X} in its mana cost, X is considered to be 0.

2023-10-13 : If the copied creature is a token, the new token that's created copies the original characteristics of that token as stated by the effect that created that token, with the exceptions noted above.

2023-10-13 : If the copied creature is copying something else, then the token enters the battlefield as whatever that creature copied, with the exceptions noted above.

2023-10-13 : The Eleventh Hour's first ability can find any card with the Doctor creature type, not cards with the word "Doctor" in the name.

2023-10-13 : The same is true for reducing the cost of Doctor spells.

2023-10-13 : The token will still have any card types it normally has, such as creature or artifact, but it will lose any non-Alien subtypes it has, such as Human or Vehicle.
