Are you wondering what the strongest cards in the new Pokémon TCG Pocket set are? Look no further than this list of the best Space-Time Smackdown cards.

This means that players actually won't be able to trade cards from the Space-Time Smackdown expansion when it launches, and will instead have to wait for that option. It also means that all the Pokemon TCG Pocket rarest cards can't be traded, so if you wanted somebody's gold Mewtwo ex, you won't get it.
