Nécrodualité

The token 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, or so on.

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

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