Double Tuning

Double Tuning (ファントムシンクロ) is special kind of Synchro Summon for which two Tuner monsters are used, rather than the usual one in the Yu-Gi-Oh! ARC-V anime.

In Episode 97 of Yu-Gi-Oh! ARC-V, Jack Atlas used Double Tuning in his Duel against Yūya Sakaki to Synchro Summon "Red Daemon's Dragon Tyrant".
