Trading is coming to Pokemon TCG Pocket later this month (with some caveats)
Briefly

The Pokémon Company revealed the trading feature for Pokémon TCG Pocket will be launched later this month, requiring players to be friends and involve item costs.
Trades in Pokémon TCG Pocket will be limited to cards of the same rarity. This includes only items with 1-4 diamond rarities or single star full-art cards.
Players will likely need to use Poké gold, an in-game currency, to complete trades, raising concerns regarding potential revenue generation from item consumption.
The official Pocket account invited players to voice their concerns regarding the trading functionality, emphasizing the need for feedback to improve the feature.
