"Millennium Seeker" Rating Score by ねこーら

Overall evaluation: The Special Summon effect alone is useful, and considering the conditions for reviving the opponent's monsters, he is useful because the higher the ATK, the easier it is to steal.
You must take 1000 or more effect damage or battles damage at once to do a Special Summon, but the easiest and most useful is the Em Trick Crown, which can be placed on GY to revive and take damage.
It's also a Level 4 Spellcaster, so it can be Xyz summoned.
Afterwards, since 《Dark Contract with the Gate》will take 1000 damage in the standby phase, there is also a way to send her on a business trip with 《D/D Lamia》.
"Supremacy Berry" is a hand, but the difficulty is high.
The second half of the effect can revive the opponent's monster, but if a monster with a higher ATK is in the opponent's main deck, it's a gambling-like thing that fails.
It's easy to use in the main deck, and when it comes to him with a high ATK, the upper limit is usually Nibiru, the Primal Being, which is 3000.
In addition, 4000 of Ritual Monster in his particular deck is good, and if you understand the deck type to some extent, the probability of success is high.
There are many Decks that use EX Deck monsters as their trump cards, so you can take advantage of them by stealing them.
It's even better if you know your opponent's deck with something like Nobleman of Extermination.
