"Naelshaddoll Ariel" Rating Score by Mr. JNK

For some reason it's rated low, but it's pretty strong and adds flexibility to Shaddoll.
I think the reverse effect will be mostly his return of Shaddoll, which he ruled out in Shaddoll Luke. Luke is the main card in his Shaddoll, so there are many opportunities to use this reverse effect. Wendy's reverse effect can also be deployed, but it is excellent in that it can be deployed without consuming his Shaddoll on Deck, as well as being able to create fusions that have been excluded.
The effect when sent to GY is also very good, basically banishing the opponent's cards and interfering with their development. Shaddoll can easily send this card to his GY during the opponent's turn, so there are many situations where this effect is effective. You can banish 3 cards at will, so you can banish all the cards that your opponent sent to his GY for development...
We can also appreciate that it will be easier to create anomalies within Shaddoll. Anomalys will stick to sticky decks, so his ability to deal with such decks will also increase.
The point to watch out for is Psychic, so he can't share spell support with DARK Shaddoll...
From the above points, I think that it will be a strong candidate for employment at Shaddoll. However, interference by exclusion selects the opponent, so you should examine adoption according to the hypothetical enemy.
