5 rulings from Wizards of the Coast
- 1 September 2023If something becomes a copy of the token, the copy is also a Reflection in addition to its other types, has haste, and isn't legendary.
- 1 September 2023Except for the listed exceptions, the token copies exactly what was printed on the original creature and nothing else (unless that permanent is itself 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 attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.
- 1 September 2023If the copied creature has {X} in its mana cost, X is 0.
- 1 September 2023If the copied creature is copying something else, then the token enters the battlefield as whatever that creature copied, with the stated exceptions.
- 1 September 2023Any enters-the-battlefield abilities of the copied creature will trigger when the token enters the battlefield. Any "as [this creature] enters the battlefield" or "[this creature] enters the battlefield with" abilities of the creature will also work.
