The card text says: Attach Koga's Ninja Trick to your Active Pokémon with Koga in its name. If this Pokémon goes to your Bench, discard this card. When your opponent attacks, you may switch this Pokémon with 1 of your Benched Pokémon (before damage or other effects of attacks).
The illustrator line reads Sumiyoshi Kizuki. I count 212 other cards in the catalog with that illustrator.
