Tuner Synchro Monsters (Japanese: シンクロチューナーモンスター Synchro Tuner Monsters) are Synchro Monsters that are also Tuner Monsters. While it was previously possible to treat Synchro Monsters as Tuners using cards such as "Lightwave Tuning", "Psychic Tuning", etc., actual printed Tuner Synchros were first introduced in Starstrike Blast. Any rules and conditions that would normally apply to either a Synchro Monster or a Tuner Monster will apply to these monsters.
In the anime, Tuner Synchros are required to perform an Accel Synchro Summon, a method of Synchro Summoning that uses Synchro Material Monsters that are themselves Synchro Monsters. A monster Summoned by such a method is known as an Accel Synchro Monster. All Accel Synchro Monsters possess an effect in the anime that allows them to be Summoned during the opponent's turn.
In the TCG/OCG, all Accel Synchro Monsters were changed to regular Synchro Monsters, and their inherent effect that allowed them to be Summoned during the opponent's turn was removed. However, in exchange, the first two Tuner Synchro Monsters to be printed ("Formula Synchron" and "T.G. Wonder Magician") gained an effect that allowed the player to conduct a Synchro Summon during the opponent's turn, as long as it was one of the Synchro Material Monsters used. In this way, those two monsters could be used to Summon any Synchro Monster during the opponent's turn, rather than just Accel Synchro Monsters.
Initially, the only Tuner Synchro monsters released were those used in the anime; however, more have been released alongside the comeback of Synchro Monsters since the release of Xyz Monsters. There are currently five Tuner Synchro Monsters in the OCG/TCG, three of which were initially shown in the anime and two of which were brand new:
|Life Stream Dragon||ライフ・ストリーム・ドラゴン||8||EARTH||Dragon||2,900||2,400|
|Phonon Pulse Dragon||波動竜フォノン・ドラゴン||4||DARK||Dragon||1,900||800|
The manga also includes an additional Tuner Synchro Monster:
