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

If the copied permanent is copying something else (for example, if the copied creature is a Clone), then the token enters the battlefield as whatever that permanent copied.

The token is an artifact in addition to its other types. This is a copiable value of the token that other effects may copy.

If you control multiple Faerie Artisans, each one’s ability only exiles tokens created with the ability of that specific Faerie Artisans.

If the permanent copied by the token had any “when [this permanent] enters the battlefield” abilities, then the token also has those abilities and will trigger them when it’s created. Similarly, any “as [this permanent] enters the battlefield” or “[this permanent] enters the battlefield with” abilities that the token has copied will also work.

A token creature that’s a copy of a player’s commander isn’t a commander.

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.
