Tuner (monster)[Notes 2]
Tuner monsters (Japanese: チューナー Chūnā "Tuner") are monsters with "Tuner" listed on the Type/Ability line. They are required for the Synchro Summon of a Synchro Monster. Normal, Effect, Pendulum, and Synchro Monsters can all be Tuner monsters, although some card effects can treat other monsters as Tuners. Flip monsters can also be Tuner monsters.
To perform a Synchro Summon, the player sends monsters they control to the Graveyard whose total Level is exactly equal to that of a Synchro Monster in their Extra Deck (including at least 1 Tuner monster), then they Synchro Summon that Synchro Monster.
Some Synchro Monsters require a specific Tuner monster to be Summoned ("Sun Dragon Inti"), or a Tuner of a specific Type ("Trident Dragion"), Attribute ("Dragocytos Corrupted Nethersoul Dragon") or Archetype ("Blackwing Tamer - Obsidian Hawk Joe"). Likewise, some Tuners can be used only for the Summon of a limited range of Synchro Monsters, such as "Brotherhood of the Fire Fist - Spirit", "Mystic Macrocarpa Seed" and "Scrap Soldier".
There are also Tuner Synchro Monsters. They tend to make Synchro Summoning easier, either by manipulating their own Level ("Phonon Pulse Dragon"), allowing its controller to Synchro Summon during the opponent's turn ("T.G. Wonder Magician"), or have effects that activate when used as a Synchro Material ("Puralis, the Purple Pyrotile"). They are also required for Accel Synchro Monsters, such as "Shooting Star Dragon".
Tuner monsters are often low in Level, usually ranging from Level 1 to 3; there are a considerable number of Tuner monsters that are Level 4—but they are generally very specific or situational—and very few that are Level 5 and above.
Many Tuner monsters have effects that assist in performing a Synchro Summon, either by Special Summoning another monster ("Deep-Sea Diva", "Masked Chameleon"), Special Summoning themselves when a condition is met ("Lady of the Lake", "Fishborg Archer") or managing the Level, Type or Attribute of monsters ("Delta Flyer", "Genomix Fighter", "Genex Ally Chemistrer", respectively); "Phantom King Hydride" can even become a non-Tuner monster for a Synchro Summon.
Some Tuner monsters, as implied by their name, have ties to sound, like "Frequency Magician", "Phonon Pulse Dragon", and the "Resonator" monsters. As such, most support cards have references to music or wavelengths, like "Natural Tune", "Resonator Call" and "Tuning".
