The free and easy Pokémon TCG Pocket made me want to collect real cards - and the hostile community immediately made me give up that dream.

The next expansion for Pokémon TCG Pocket is on its way, and you won’t have long to wait before more than 100 new cards are taking up space in your digital bind

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.
