Of all the new cards being added to Pokemon TCG Pocket with the upcoming Space-Time Smackdown set, one has the potential to be a meta game-changer.

The Space-Time Smackdown expansion will focus on the Sinnoh region and will feature Dialga and Palkia as the figurehead Pokémon for the two new packs. The expansion also introduces Tool-type cards that will provide your Pokémon with even more support in battle.

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.

When you’ve filter through your collection in Pokémon Trading Card Game Pocket, you may notice an option to filter for Pokémon Tool cards. There’s nothing ever there, because Pokémon TCG Pocket doesn’t currently have any Pokémon Tool cards. But that appears to be changing with the Space-Time Expansion announced Thursday.

The name and release date of Pokemon TCG Pocket's new set of cards has been revealed. Trading also has a release date but there are now even more restrictions.

New Pokemon TCG expansion A2 Space-Time Smackdown focuses on Generation 4's Diamond and Pearl. Only a handful of cards from among more than 240 were revealed, leading players to predict the meta. Honchkrow,
