Mobile games frequently have some way to redeem offers from third-party collaborations, and Pokemon TCG Pocket is no exception. Unfortunately, the method for redeeming the codes you receive for buying certain products or participating in an event isn't explained in the app.

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.

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.
