Unlike TMs, TRs can only be found and obtained in the Wild Area. Every last TR that is known to exist can be obtained as a Drop Reward from a Max Raid Battle. Depending on the Type of Pokemon you defeat, you will receive various TRs that are the same type as the Raid Boss you defeat. Additionally, all TRs can be purchased from the various staff members throughout the Wild Area on a rotational basis.
