Many Tuner Monsters are designed to Synchro Summon specifically one monster. Sometimes, this is made obvious by the fact that the Tuner Monster literally must be used for the Synchro Summon (for instance, Junk Synchron and Junk Warrior). Other times, the Tuner has an effect that lets you special summon a monster with the perfect level for the Synchro Summon (a good example would be Black Salvo with Dark Strike Fighter).
