From Bulbapedia, the community-driven Pokémon encyclopedia.
Psychic Switch is a 
type deck found in the Gym Challenge Strategy Guide. The deck is classified as one of the "hard-core" decks in the book, containing more rare cards than the easy-to-build decks.
Description
Rocket's Mewtwo is a good Pokémon in its own right. But "Psychic Switch" makes this Genetic Pokémon even better. The idea here is to use Sabrina's Alakazam's Psylink power to copy Rocket's Mewtwo's Juxtapose attack. Use the Sabrina's ESP Trainer card to give you an even better chance of making Psylink work.
You can also play some cool Psychic tricks with this deck, like healing your opponent's Pokémon with Sabrina's Jynx's Helping Hand attack and drawing a lot of cards for yourself. Then you can use Rocket's Mewtwo's Juxtapose attack to shift damage from Rocket's Mewtwo to the Defending Pokémon again. Sabrina's ESP works really well with Sabrina's Kadabra's awesome Life Drain attack, too, giving you a really good chance to knock even the biggest Pokémon down to only 10 Hit Points.
