PSA: Trading Is Finally Live In Pokémon TCG Pocket, But It's A Real Headache
All trades require an adequate amount of Trade Stamina — a new bar that replenishes over time, much like Wonder Stamina. You'll recover one Trade Stamina 'piece' every 24 hours and you can hold a maximum of five 'pieces' at any one time. Naturally, you can use Trade Hourglasses or Poké Gold to recover Trade Stamina quicker.
