The Pokémon Company International has announced an errata change to the Cyrus Prism Star card (120/156). Details of this change are below and have been added to our TCG Dex.

Errata for Cyrus Prism Star in Pokémon TCG: Sun & Moon Ultra Prism

This text change for the Supporter card Cyrus Prism Star will be effective immediately.

Due to an error in the card text for Cyrus (Sun & Moon—Ultra Prism, 120/156), the first part of this card will be changed. The original text for this Supporter card says:

You can't play this card if you don't have any or Pokémon in play.

Your opponent chooses 2 Benched Pokémon and shuffles the others, and all cards attached to them, into their deck.

The text will be changed to match the original intention of the card, which is that a player's Active Pokémon must be a or Pokémon.

The new Cyrus text will say:

You can play this card only if your Active Pokémon is a or Pokémon.

Your opponent chooses 2 Benched Pokémon and shuffles the others, and all cards attached to them, into their deck.

Effective immediately, Cyrus will use this updated text instead of the original text. This will be reflected in the Pokémon TCG Errata document.
