From Bulbapedia, the community-driven Pokémon encyclopedia.
The Easy-to-Build Psychic Deck is a predominantly type deck found in the Team Rocket Strategy Guide. The deck is considered easy-to-build as it contains few rare cards, with the aim that a player of any age or skill level could complete it.
Except for Gastly, Haunter, and Gengar, all Psychic Pokémon have a Weakness to Psychic Pokémon! Almost every Psychic deck should have these Pokémon. It's also helpful to add Pokémon with Resistance to Psychic—like Rattata—just in case your opponent plays Gastly, Haunter, and Gengar, too.
Look what happens when you combine Here Comes Team Rocket! with Rattata's Pokémon Power: Trickery. You can choose to draw any one of your Prizes each turn instead of the top card of your deck. You can even use Dark Kadabra's Pokémon Power: Matter Exchange to draw the card right away. To make sure you aren't switching the Prize you want to draw with a better card, you can use Pokédex to look at the top five cards of your deck and put the ones you don't want—like extra Energy—on top. Then use Trickery to switch it with the Prize card you do want. If you change your mind, you can always grab the card later.
