The rarest cards in Pokémon TCG Pocket either have very low pull rates, can only be obtained by meeting certain requirements, or are exclusive to limited-time events. The rankings will change as new cards and packs are added to the game.

The creators of Pokémon TCG Pocket have issued a warning to all players not to tamper with game data or participate in real money trades, or risk getting their accounts banned. The crackdown comes right before card trading and a new Space-Time Smackdown set are added to the mobile hit.

The next major Pokémon Trading Card Game Pocket update, dubbed Space-Time Smackdown, is scheduled for Jan. 29, but several cards are already starting to appear online, presumably through datamining. Let’s break down some highlights.
