7 rulings from Wizards of the Coast
- 8 November 2016If the copied permanent has {X} in its mana cost, X is considered to be 0.
- 8 November 2016If 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.
- 8 November 2016The token is an artifact in addition to its other types. This is a copiable value of the token that other effects may copy.
- 8 November 2016If you control multiple Faerie Artisans, each one’s ability only exiles tokens created with the ability of that specific Faerie Artisans.
- 8 November 2016If 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.
- 8 November 2016A token creature that’s a copy of a player’s commander isn’t a commander.
- 8 November 2016The 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.
