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

If the copied permanent has in its mana cost, X is 0.

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

If the copied permanent is a token, the token that’s created copies the original characteristics of that token as stated by the effect that created that token, with the stated exceptions.

Except for the listed exceptions, the token copies exactly what was printed on the original permanent and nothing else (unless that permanent is copying something else or is a token; 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.
