Training and trading

How do I teach a move?

Use a TM or HM from the Bag and choose a compatible Pokémon. If it already knows four moves, you choose which one to replace. A successful teach uses up the TM. Declining the change keeps it in your Bag. HMs can teach the same move to more than one Pokémon.

Can I evolve Haunter when nobody else is online?

In Kanto, take Haunter to the right-hand counter upstairs in a Pokémon Center. The Link Trade attendant can evolve eligible members of your party while you keep them. This also works for Kadabra, Machoke, and Graveler. For evolutions that require a held item, give the Pokémon that item before you talk to the attendant. An Everstone prevents the evolution.

How do player trades and mail work?

• Direct trade. Invite the other player, choose your offer, and check what they put in the trade window. Both players lock their offers and confirm the exchange.
• Global Trade Link. Browse the listed Pokémon and check the price before confirming a purchase. The Pokémon arrives by delivery mail. Open the message and claim the attachment. The filter searches only the listings on the page you have loaded.
• Mail. A trainer can send a message with money, an item, or a Pokémon attached. The recipient opens their inbox and claims the attachment.
• Wonder Trade. When enabled, you can offer an eligible party Pokémon for a surprise Pokémon from the pool. The panel shows which members you can offer and how long you have to wait between exchanges.
