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.

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.

There are a number of ways to build up Palkia ex in Pocket, but we found it worked best alongside Vaporeon, Manaphy, and a singular Articuno ex for easy Energy Token control and immense damage output. Building this deck may take newer players a little more time, as it features cards from every set and themed booster pack in the game so far.
