"Majesty's Fiend" Rating Score by シエスタ

It's powerless against permanent effects, but compared to Void, it's strong against lower-level monster effects, and currently, this effect is as influential as Void or even more influential.
Compared to Void, his defensive power is plainly low, and since he has the same status as Monarch, he can receive King Monarch's support, which is rather an advantage.
Angel 07 with the same effect exists, and his Special Summon is also possible over there, but it is not effective unless it is a Tribute Summon, and it is somewhat heavy as the highest grade.
Although the RBI is almost the same and there are differences in races, this one is easier to use overall.
However, it is also painful that the hand trigger monsters of the required class, which have a strong influence, cannot be used at all, and it is better to rely on magic and traps for defense.
Also, he is powerless against magic and traps, and now his Monarch RBI is not so high and does not have much effect on summoning actions, so if his deck has high beats and high deployment power, high RBI will be issued from EX. It's not uncommon for it to end quickly. If you want to make it more rock solid, you want to keep the back as solid as the void.
There are quirks, but I think it's a versatile and powerful advanced.
