How to Battle Other Players: the missing first guide
A Spanish-speaking player on the Tournaments page asked how to actually battle other people, and we had no answer anywhere on the site. New [How to Battle Other Players](/guides/how-to-battle) guide covers Ranked and Casual matchmaking, Private Battles by Room ID, adding friends, and how Online Competitions work, with the exact in-game menu steps for each. Steps verified against Nintendo Support and Serebii. Linked from the Tournaments page so nobody lands there stuck again.
