The ones (yes, multiple) I transferred had Psychic, Shadow Ball, Signal Beam, & Water Pulse, and they all checked out fine. Dunno what's Katze's Jirachi's problem =/Stefan wrote:
Maybe the moves are the issue? This can if the pokemon has something that the Pokemover doesn't accept it for whatever reasons cause this Problem. (Would wonder what moves Blaze's WISHMKR Jirachi has to compare it with Katze's one)
(And I doubt this has any relevancy, but all the Jirachi I transferred had Pokérus.)
