The Pokémon Company attributed the controversy to a production issue as the Wisdom of Sea and Sky expansion pulls Ho-Oh art amid plagiarism backlash.

While you can now start collecting Pokémon TCG Pocket’s Johto-themed Wisdom of Sea and Sky expansion, two of the set’s rarest cards are being changed in response to concerns about art theft.
