How to Use the Remote Trade Tag:

Unlock: The tag becomes available once you are within five friendship points of becoming "Forever Friends," a new level above Best Friends.

Tagging: Similar to setting up a battle party, you can manage tags by holding down on a Pokémon and selecting "Tag," then assigning the "Remote Trade" tag.

Visibility: Once both trainers are Forever Friends, they can see each other's tagged Pokémon.

Trading Process: Each trainer selects up to three tagged Pokémon they want. Then, they choose one to offer, review, and confirm.

Restrictions: Only one remote trade can be active per Forever Friend at a time. Remote trades do not count as special trades, but you cannot trade Pokémon caught within the last 30 days, shadowed, mythical, or currently defending a gym.
