Twilight Diviner

Any enters abilities of the copied creature will trigger when the token enters. Any "as [this creature] enters" or "[this creature] enters with" abilities of the copied permanent will also work.

If the copied creature has {X} in its mana cost, X is 0.

The token created by Twilight Diviner's last ability copies exactly what was printed on the original permanent and nothing else (unless that permanent is copying something else; see below). It doesn't copy whether that permanent is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.

If the copied creature is copying something else, then the token enters as whatever that creature copied.
