"Millennium Seeker" Rating Score by みめっと

In addition to the self-SS effect that triggers a certain amount of damage, it is a monster with the image of Shadi, so it's just an effect that just revives one monster from the opponent's GY. A monster that has elements or rules added to make it look like it.
If you target monsters with 20 RBI or more that have been Special Summoned from EX and sent to GY, I think you can successfully effect the effect against most Decks where EX monsters are the main force. If you have Nibiru or Pancra in your Deck, you can't do that, and if you lose, your opponent will search for your chosen card, so there is a certain risk.
Conversely, if you use the effect on Nibiru or Pancra, depending on the opponent's deck, it will rarely be blocked.
Again, for the effect of just reviving one monster from the opponent's GY, it's not good to have to cross a slightly dangerous bridge where the opponent may search for any monster. With that impression, you can choose not to select anything & the selected monster will return to the Deck even if it can't be searched, so you can get information ads or extract Nibiru, which is planned to be sent to GY by erasure. Everything is left to the opponent's will, so I feel like I didn't write anything particularly strong, including the activation effect that activates on the field.
