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.

Pokemon Trading Card Game Pocket introduces trading feature, initially limited to select cards and timed. Real money trading is explicitly prohibited in the game, with consequences for violators. Trading restrictions and time-gating aim to deter profiteering and prevent quick completion of Card Dex.
