"Thestalos the Shadowfire Monarch" Rating Score by シエスタ

He is the new Monarch King who appeared in the 12th term, and from this time on, he has a status that exceeds even the highest Monarch, and has elements that combine the two Monarch Kings.
Furthermore, if the conditions are met, he can be summoned while processing the opponent's monsters like Kaiju. It's not easy, but with its own effects, it can destroy the opponent's cards, and if used in conjunction with 《Escalation of the Monarchs》, it can also interfere.
With effects such as Testaros + Gaius, you can expect high firepower by erasing a large number of opponent cards.
Since he is a ban, he doesn't even use GY, and since he doesn't target, the removal quality is good. Like Gaius, you can also exclude yourself, in which case it will be 3000 burns, so you can expect it to be a leading firepower.
However, in order to exert the additional effect, it is necessary to have Tribute Summon level 8 or higher, which is quite heavy.
Also, at present, he doesn't support King Monarch's support, and it's somewhat dependent on the opponent, and it's worrisome that without additional effects, it's not much different from Honkeen Monarch.
I have the impression that it is a card that has an impact but cannot be said to be easy to use at present. I look forward to the future development of this series.
