Resonator

Resonators are a set of Fiend-type Tuner monsters used by Jack Atlas in the Yu-Gi-Oh! 5D's anime. They tend to have useful abilities in Synchro Summoning.

Currently, the only known Resonators are Dark Resonator, Flare Resonator, Creation Resonator, Barrier Resonator, and Force Resonator.

So far, Barrier Resonator and Force Resonator are the only Resonator cards that are not Level 3.

Earth is only Attribute without a Resonator card so far, though it will probably in later time. it might be called "Ās Resonator" if it comeout in OCG/TCG
