"Chain Resonator" Rating Score by TAG

The drawback is that you have to use summoning rights, but being able to recruit a Resonator from the Deck is usually powerful. With the current card pool, Crimson Resonator and a level 4 monster that can be Special Summoned can be synchronized while still retaining the right to summon, so it's a decent card.
If you use Crimson Resonator's (2) effect to recruit 《Soul Resonator》from the Deck, you can search for this card as well.
However, the fact that this card is LIGHT is more important than its effect, and when deploying using Chaos Ruler, the Chaotic Magical Dragon and Bystial Dis Pater, it can be used as a cost to be removed by Chaos Ruler's (2) effect. This is a decisive difference from the Resonator of The advantage is that it's level 1 and easy to use to synchro summon "Hot Red Dragon Archfiend Abyss".
His Resonators with the same attribute are 《Barrier Resonator》and 《Mirror Resonator》, but since the effects of each are difficult to use, this card is almost the only card to choose.
If you add this card from the aforementioned Crimson Resonator, you will have a large synchro of 《Red Supernova Dragon》, 《Bystial Dis Pater》and 《Hot Red Dragon Archfiend Abyss》in the final board, and you will be able to compose a tremendous control board.
Unfortunately, it was not reprinted in Jack Strak, so depending on Red Archfiend's success, the price may rise.
