Errata for Cyrus Prism Star in Pokémon TCG: Sun & Moon Ultra Prism
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 has been 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 says:
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.
