"Chain Resonator", "Dark Resonator", "Synclone Resonator" and "Mirror Resonator" with "Influence Dragon"
"Resonator" is an archetype of Fiend-Type Tuner monsters used by Jack Atlas and his imposter in the Yu-Gi-Oh! 5D's anime. Their effects are centered around being useful towards Synchro Summoning and stalling. There is one "Resonator" for each Attribute. Most of these cards wield a tuning fork and a mallet.
In the anime, "Clock Resonator" is the only non-Fiend-Type "Resonator", although it was changed to a Fiend-Type when released in the OCG. The six "Resonator" monsters that were released in the OCG are each a different Attribute.
A "Resonator" Deck can be used in many different ways. Most use the classic, Level 5 and Level 3 setup for easy "Red Dragon Archfiend". Cards such as "The Tricky" or "Cyber Dragon" work really well in this kind of Deck. "Instant Fusion" is also an excellent choice. "Resonator Call" is the "Reinforcement of the Army" for the "Resonator" archetype. "Dark Necrofear" is also another option for a "Resonator" Deck.
