Calix may be the target of its own constellation ability. This includes when Calix itself enters the battlefield. |

Calix's last ability doesn't target any permanent. You choose which nonlegendary enchantment you control you're creating a token copy of, if any, as the ability resolves. No player may take any actions between your choice and the creation of the token. |

Once you choose to create a token using the last ability, that ability won't trigger again that turn. Additional instances of the ability that are already on the stack will resolve but will have no effect. |

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. |

If the copied permanent has  in its mana cost, X is 0. |
| 5/12/2023 |
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. |
| 5/12/2023 |
If the copied permanent is copying something else, then the token enters the battlefield as whatever that permanent copied. |
| 5/12/2023 |
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. |
